Nerve inflammation in the foot
Diabetic neuropathy is one of the nerve damages that can be seen on the foot. In diabetics with poorly adjusted blood sugar levels, toxic metabolic products are stored in the nerve tissue after a long period of time with elevated blood sugar levels. This causes the nerves to lose their function.
This nerve degeneration often starts at the feet and rises symmetrically. This leads to malpositioning of the feet and thus to incorrect strain and wounds.Since the perception of pain is also impaired, the wounds are often not noticed at first. These symptoms are summarized under the term “diabetic foot“. Another cause of a “diabetic foot” is a reduced blood supply to the foot caused by arteriosclerosis of the leg vessels.
Nerve inflammation in the thigh
The skin of the thigh is sensitively supplied by nerves from the plexus lumbalis. If one of these nerves is damaged, the typical symptoms of an inflammation of the nerves in the area of the thigh and pain in the thigh can occur. In most cases, pain also occurs in other parts of the body at the same time.
For example, a lesion of the genitofemoral nerve causes pain in the upper inner side of the thigh and pain in the groin and, in men, in the testicles and, in women, the labia majora. Pain associated with the sciatic nerve occurs on the back of the thigh, also on the lower leg and/or foot. If the nervus femoralis is damaged, there is a loss of sensitivity at the front of the thigh.
In addition, motor failures can occur, whereby the hip can no longer be bent and the knee can no longer be stretched. In the case of pain in the thigh alone without other symptoms, a disturbance of the obturatorial nerve may be considered. This causes pain in the lower part of the inner side of the thigh.
Possible causes are compression or damage to the nerve as part of a herniated disc, pelvic fracture or other processes in the pelvis. Only pain or sensory disturbances on the outside of the thigh and on the anterior superior iliac spine can be caused by a lesion of the nervus cutaneus femoris lateralis. This clinical picture is called Meralgia paraesthetica, in which the nerve is compressed below the inguinal ligament.
