Frequent soreness in the thighs is usually seen after strenuous exercise and frequent activity of the thigh muscles, resulting in minor muscle strains and strain, and after these conditions have occurred, strict warmth is not applied, resulting in a cold condition in the thigh muscles. After the formation of a sterile inflammatory lesion, if the cold and blood circulation is slowed down, it will lead to the accumulation of inflammatory metabolites, which will stimulate the peripheral nerves and cause soreness and pain. After this situation, you should take strict rest, let the muscles of the thigh fully relax, and take oral non-steroidal anti-inflammatory and analgesic drugs, such as loxoprofen sodium and diclofenac sodium, to reduce the local inflammation and pain; take oral Chinese medicine that activates blood circulation and relieves blood stasis, soothes the muscles and improves the circulation, such as Da Qi Li capsule, which can increase blood circulation. Hot compresses can also be applied 3-5 times a day for 20-30 minutes each time, which can effectively metabolize inflammatory metabolites and promote healing after blood circulation is accelerated. In addition, oral administration of Eperisone Hydrochloride tablets, a muscle relaxant, can effectively reduce the tension of the thigh muscles, and after muscle relaxation, can further promote recovery. After the above treatment for 3-5 days, the symptoms will be significantly improved.
