For the question of how to do sore legs and weakness, first of all, we need to clarify what causes sore legs and weakness in order to actively carry out symptomatic treatment. If it is due to local muscle strain, thus appearing sore legs and weakness. It is necessary to stay away from the straining environment, apply local hot compresses or massage, apply blood-stasis activating medication, apply blood-stasis activating ointment, such as blood-stasis activating and pain relieving cream, and cooperate with acupuncture and other physiotherapy methods, it will slowly get better. If the patient has local spinal nerve compression, and the leg is sore and weak, and the symptoms are relatively mild, choose conservative treatment. Avoid sitting and standing for a long time, apply local heat, and take oral non-steroidal anti-inflammatory and analgesic drugs and nerve-nourishing drugs, such as Nimesulide capsules and methylcobalamin. However, if the symptoms still do not improve after treatment and recurrent attacks occur, it is recommended to seek medical attention in a timely manner and actively undergo surgery if necessary.
