Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
The lateral femoral cutaneous nerve (LFCN) originates from the lumbar plexus and contains fibers from lumbar nerves L2 and L3. [7] [4] [2] [3] The LFCN then traverses to the lateral border of the psoas major muscle, crosses the iliacus muscle, and continues to the anterior superior iliac spine (bony landmark).
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet.

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).
What causes lower left abdominal pain? Lower left abdominal pain can have many causes, ranging from minor to serious, says Andrew Boxer, M.D., gastroenterologist of Gastroenterology Associates of ...
Erythromelalgia in left hand: Specialty: Oncology: Causes: There was a study done in 2013 where two Vietnamese patients were diagnosed with primary erythromelalgia. Patient A was a 33-year old female diagnosed with primary erythromelalgia at age 30 and suffered from burning and pain in her feet since she was 8 years old (Wu et. al 2013).
Angiograms of a patient diagnosed with popliteal artery entrapment syndrome of the left lower extremity. Image A shows a neutral popliteal artery before provocative maneuvers. Images B and C show the obstruction (orange arrows) enhanced with provocative maneuvers of plantar flexion and dorsiflexion, respectively.
Usually, in this case, motor function of the lower leg will not be impaired. This is a key distinction between saphenous nerve neuropathy and lower back radiculopathy. Saphenous nerve neuropathy only demonstrates sensory alterations, while lumbar radiculopathy will affect the motor, sensory, and deep tendon reflexes of the lower leg. [6]
