Piriformis syndrome is often left undiagnosed and mistaken with other pains due to similar symptoms with back pain, quadriceps pain, lower leg pain, and buttock pain. These symptoms include tenderness, tingling and numbness initiating in low back and buttock area and then radiating down to the thigh and to the leg. [72]
Examples of paresthesias (abnormal sensations but not unpleasant) and dysthesias (abnormal sensations that are unpleasant) are burning, tingling, numbness, stinging, hypersensitivity, and itching. The symptom intensity can be mild to severe in a way that limits function due to pain. [5] Activity and position can affect the symptoms.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Weakness or numbness may occur in various parts of the affected leg and foot. [3] About 90% of sciatica is due to a spinal disc herniation pressing on one of the lumbar or sacral nerve roots. [4] Spondylolisthesis, spinal stenosis, piriformis syndrome, pelvic tumors, and pregnancy are other possible causes of sciatica. [3]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
Paresthesias are usually painless and can occur anywhere on the body, but most commonly occur in the arms and legs. [1] The most familiar kind of paresthesia is the sensation known as "pins and needles" after having a limb "fall asleep". A less well-known and uncommon paresthesia is formication, the sensation of insects crawling on the skin.
Proximal diabetic neuropathy, also known as diabetic amyotrophy, is a complication of diabetes mellitus that affects the nerves that supply the thighs, hips, buttocks and/or lower legs. Proximal diabetic neuropathy is a type of diabetic neuropathy characterized by muscle wasting, weakness, pain, or changes in sensation/numbness of the leg.
Generally, diseases outlined within the ICD-10 codes O00-O99 within Chapter XV: Pregnancy, childbirth and the puerperium should be included in this category. v t
