Sciatica

Sciatica is described as pain, numbness or tingling in the leg due to compression of the sciatic nerve. The sciatic nerve runs down the back of each leg from the lower spine. The pain associated with sciatica can range from dull ache to excruciating pain that makes movement difficult. The pain may be felt in the buttock, down the back of the leg, below the knee and in the foot.


Causes of sciatica


  • Disc herniation
  • Pelvic fracture
  • Spinal tumors
  • Pelvic injury
  • Pain along one side of the body
  • Worsening in cold weather
  • Osteoarthritis causing pressure on the sciatic nerve

A physical examination along with checking of reflexes on bending, lifting the leg etc are done. X-ray and MRI might be done. Typically sciatica is indicative of another medical problem; which must be attended to. NSAIDs and ice packs provide relief from the pain. Lifting of heavy objects and strenuous back bending are to be avoided. Physical therapy, massage therapy and stretching exercises might help in tackling chronic sciatica.

Physiotherapy

Physical therapy also known as physiotherapy, includes evaluating, diagnosing and treating numerous disorders and disabilities through the physical way. This branch of medicine helps people restore, retain and maximize their strength, function, movement and overall well-being.

People who practice this branch of therapy are called physiotherapists. Diagnosis, treatment and rehabilitation of patients are their main areas of work. They primarily work with physical disorders and disabilities. Physiotherapy helps a person


  • Become flexible
  • Improve mobility
  • Reduce pain
  • Stay active
  • Prevent injury
  • Recover from injury

Physiotherapy helps the human body to remain functional. Physiotherapy is recommended when the human body suffers some physiological trauma. During physiotherapy the patient is examined physically and if required imaging studies are carried out so as to decide the right type of therapy. It is recommended in the following conditions:



Heat therapy: Heat therapy improves the blood flow to the injured area thus speeding up healing. Heat therapy also loosens the tight tissues thereby relieving pain. Various heat treatments include ultrasound, hot pack, infrared heat, Paraffin wax bath, Diathermy

Cryotherapy: Cold therapy helps in minimizing the swelling and pain. It is very useful in acute injuries. Various treatments include ice massage and ice pack application

Strengthening exercises with Physical Therapy: Certain conditions may have caused the muscles to weaken, there are certain types of exercises aimed at strengthening the muscles thereby helping rehabilitation and improving performance.

Range Of Motion exercises: ROM exercises help in improving and maintaining the flexibility of joints. They also help in reducing the stiffness of the joints. Various exercises include:

Passive Range of Motion exercises: (PROM)

Active Range of Motion exercises: (AROM)

Active Assistive Range of Motion exercises: (AAROM)

Soft tissue mobilization/Therapeutic massage:This relaxes the tight muscles thus relieving pain and reducing swelling

Electrical stimulation: This method is used to prevent muscle atrophy in people with paralysis. Electrodes are placed on the surface of the skin thus causing the muscle to shorten.

TENS: Transcutaneous Electrical Nerve Stimulation is a type of never stimulation wherein a low degree electrical current is passed through the surface of the skin to the affected part. This process helps in relieving pain momentarily.


Other types of physical therapy treatment include taping, bandaging, joint mobilization, ergonomic training, postural training, balance exercise, traction, fitting of orthosis, etc. Physiotherapy has various specializations like geriatric, pediatric, orthopedic, neurological, sports, cardiovascular and pulmonary.



Paraesthesias

Paraesthesias, also spelled paresthesias, is a medical term that refers to abnormal sensations in the body, typically involving a feeling of tingling, pricking, numbness, or "pins and needles." These sensations are often described as uncomfortable or abnormal and may be experienced in various parts of the body, such as the hands, feet, arms, legs, or other areas.

Paraesthesias

Paraesthesias can be caused by a variety of underlying medical conditions or factors, including:

  • Nerve Compression or Irritation: Pressure on or damage to nerves, such as in conditions like carpal tunnel syndrome or sciatica, can lead to paraesthesias.
  • Nerve Disorders: Diseases that affect the nervous system, like peripheral neuropathy, multiple sclerosis, or diabetic neuropathy, can result in abnormal sensations.
  • Poor Circulation: Reduced blood flow to specific body parts can lead to paraesthesias, as tissues may not receive sufficient oxygen and nutrients.
  • Vitamin Deficiencies: Deficiencies in certain vitamins, particularly B vitamins like B12 and folate, can contribute to nerve-related symptoms, including paraesthesias.
  • Infections and Inflammatory Conditions: Conditions like shingles, Lyme disease, or autoimmune diseases can cause nerve inflammation and lead to abnormal sensations.
  • Medications and Toxins: Some medications or exposure to toxins can induce paraesthesias as a side effect.
  • Trauma or Injury: Physical injury or trauma to nerves or tissues can result in temporary or chronic paraesthesias.
  • Psychological Factors: In some cases, paraesthesias may be related to psychological stress or anxiety.

Some medications have the potential to affect the nervous system and cause these symptoms. It's important to note that individual responses to medications can vary, and not everyone will experience paraesthesias as a side effect. Here are some categories of medications and specific drugs that are known to be associated with paraesthesias:

  • Chemotherapy Drugs: Several chemotherapy agents, such as paclitaxel, vincristine, and cisplatin, can cause peripheral neuropathy, leading to paraesthesias in the hands and feet.
  • Anticonvulsant Medications: Some anticonvulsants, including phenytoin and carbamazepine, may cause paraesthesias as a side effect.
  • Antidepressant Medications: Tricyclic antidepressants like amitriptyline and selective serotonin reuptake inhibitors (SSRIs) like fluoxetine have been associated with paraesthesias in some individuals.
  • Antiretroviral Drugs: Certain medications used to treat HIV, such as zidovudine and didanosine, may lead to peripheral neuropathy and paraesthesias.
  • Antibiotics: Some antibiotics, particularly fluoroquinolones (e.g., ciprofloxacin), have been linked to peripheral neuropathy and paraesthesias.
  • Antifungal Medications: Antifungal agents, such as fluconazole, can occasionally cause peripheral neuropathy and associated symptoms.
  • Antihypertensive Medications: Diuretics and calcium channel blockers are classes of drugs that may rarely induce paraesthesias.
  • Statins: Statin medications used to lower cholesterol levels, like atorvastatin and simvastatin, have been reported to cause muscle-related paraesthesias in a minority of users.
  • Immunomodulatory Drugs: Medications used for autoimmune diseases, like interferons and monoclonal antibodies, can result in paraesthesias.
  • Local Anesthetics: Certain local anesthetics used in medical or dental procedures may lead to temporary paraesthesias.

Vitamin B3, also known as Niacin, is an essential nutrient that plays a crucial role in various bodily functions, including energy metabolism and maintaining the health of the nervous system. While niacin deficiency can lead to neurological symptoms, including paraesthesias (abnormal sensations like tingling or numbness), it is rare in well-nourished individuals.

However, high doses of niacin, often used in the treatment of certain medical conditions like high cholesterol, can indeed cause paraesthesias as a side effect. This is a well-known side effect of niacin therapy and is commonly referred to as the "niacin flush." The niacin flush involves a warm, tingling sensation, often accompanied by redness and flushing of the skin, particularly on the face and upper body. Some people may describe it as a temporary, uncomfortable form of paraesthesias.

The niacin flush is usually harmless and transient, lasting for about 15-30 minutes after taking a high-dose niacin supplement. Over time, the body may develop some tolerance to this side effect. Nevertheless, individuals who experience severe or persistent paraesthesias or other adverse effects from niacin should consult their healthcare provider. It's important to take niacin supplements as directed by a healthcare professional, as high doses can have potential side effects, including liver toxicity, gastrointestinal disturbances, and other adverse reactions.


Diagnosis and management of paraesthesias typically involve a thorough medical history, physical examination, and, if necessary, further diagnostic tests such as nerve conduction studies, electromyography, blood tests, or imaging studies. The underlying cause of paraesthesias must be identified and treated accordingly. Management may involve addressing the primary medical condition, physical therapy, medication, or lifestyle changes to alleviate the abnormal sensations and improve the patient's overall well-being.
