Numbness in the lateral thigh, this condition is usually lateral femoral cutaneous neuritis, which is a cutaneous nerve, when stimulated by local inflammation, irritation, trauma, cold and other reasons, it may lead to local edema squeezing the cutaneous nerve, resulting in ischemia of the nerve bundle, and numbness of the lateral femoral cutaneous nerve in the location of the lateral thigh distribution area. This situation can take the following treatment measures: First, you can take oral anti-inflammatory and pain-relieving drugs, such as nimesulide, loxoprofen sodium, diclofenac sodium can effectively relieve the local inflammatory edema, reduce the stimulation of the lateral femoral cutaneous nerve, the symptoms of numbness can be improved. Secondly, oral administration of methylcobalamin tablets or adenosine cobalamin tablets can nourish the lateral femoral cutaneous nerve and promote the recovery of nerve function. Thirdly, you can take oral Chinese medicine to activate blood circulation and relieve blood stasis, such as Guilong Tendon and Bone Capsules and Tong Piao Capsules, which can effectively increase the local arterial supply and promote venous return, so that the ischemia of the lateral femoral cutaneous nerve can be effectively improved. Fourth, if the above treatment is not effective, the lateral femoral cutaneous nerve from the fascial exit location can be closed injection, usually selected compound betamethasone, as well as lidocaine hydrochloride injection after mixing closed injection. It can effectively reduce the local inflammatory stimulation, and the ischemia of the nerve bundle can be significantly improved.
