Meralgia paresthetica or meralgia paraesthetica is pain or abnormal sensations in the outer thigh not caused by injury to the thigh, but by injury to a nerve which provides sensation to the lateral thigh. Meralgia paresthetica is a specific instance of nerve entrapment. [5] The nerve involved is the lateral femoral cutaneous nerve (LFCN).
Levator ani syndrome is a condition characterized by burning pain or tenesmus of the rectal or perineal area, [1] caused by spasm of the levator ani muscle. [ 2 ] [ 3 ] [ 4 ] The genesis of the syndrome is unknown; however, inflammation of the arcus tendon is a possible cause of levator ani syndrome.
Burning dysesthesia might accurately reflect an acidotic state in the synapses and perineural space. Some ion channels will open to a low pH, and the acid sensing ion channel has been shown to open at body temperature, in a model of nerve injury pain. Inappropriate, spontaneous firing in pain receptors has also been implicated as a cause of ...
Symptoms are pain or dysthesias (abnormal sensation) in the buttocks, hip, and posterior thigh with or without radiating leg pain. Patients often report pain when sitting. [1] The two most common causes are piriformis syndrome and fibrovascular bands (scar tissue), but many other causes exist. [2]
Greater trochanteric pain syndrome (GTPS), a form of bursitis, is inflammation of the trochanteric bursa, a part of the hip.. This bursa is at the top, outer side of the femur, between the insertion of the gluteus medius and gluteus minimus muscles into the greater trochanter of the femur and the femoral shaft.
Rest pain is a continuous burning pain of the lower leg or feet. It begins, or is aggravated, after reclining or elevating the limb and is relieved by sitting or standing. It is more severe than intermittent claudication, which is also a pain in the legs from arterial insufficiency. [citation needed]
In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscle, outside the femoral sheath, and lateral to the femoral artery. After a short course of about 4 cm in the thigh, the nerve is divided into anterior and posterior divisions, separated by lateral femoral circumflex artery. The branches are shown below: [1]
The International Association for the Study of Pain (IASP) defines chronic pain as a general pain without biological value that sometimes continues even after the healing of the affected area; [8] [9] a type of pain that cannot be classified as acute pain [b] and lasts longer than expected to heal, or typically, pain that has been experienced on most days or daily for the past six months, is ...
