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).
Positive sensory symptoms are usually the earliest to occur, particularly tingling and neuropathic pain, followed or accompanied by reduced sensation or complete numbness. Muscle weakness and muscle atrophy may only be present if the entrapped nerve has motor fibers (some nerves are only sensory). Weakness and atrophy is a much less common ...
Here you can see a typical test where the first lactate threshold is at around 210-215 power output and their second lactate threshold is at 260-265.
Disuse is a common cause of muscle atrophy and can be local (due to injury or casting) or general (bed-rest). The rate of muscle atrophy from disuse (10–42 days) is approximately 0.5–0.6% of total muscle mass per day although there is considerable variation between people. [5]
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.
Over time, alcoholic polyneuropathy may also cause difficulty swallowing , speech impairment , muscle spasms, and muscle atrophy. [ 5 ] In addition to alcoholic polyneuropathy, the individual may also show other related disorders such as Wernicke–Korsakoff syndrome and cerebellar degeneration that result from alcoholism-related nutritional ...
The insufficiency of energy, i.e. sub-optimal aerobic metabolism, generally results in the accumulation of lactic acid and other acidic anaerobic metabolic by-products in the muscle, causing the stereotypical burning sensation of local muscle fatigue, though recent studies have indicated otherwise, actually finding that lactic acid is a source ...
Paresthesia, also known as pins and needles, is an abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause. [1] Paresthesia may be transient or chronic, and may have many possible underlying causes. [ 1 ]
