There are many causes of hip and thigh pain on one side, and the common causes are as follows: first, it may be caused by a herniated lumbar disc pressing on the sciatic nerve, and if this is the cause, in addition to hip and thigh pain on one side, it is often accompanied by symptoms of lumbar pain. The sciatic nerve can be stimulated and the meridians and blood in the waist and legs can be unblocked through acupuncture, massage therapy, ultrasonic wave therapy and ultrasound therapy. As long as the meridians and blood in the waist and legs are unblocked, the painful symptoms can be greatly reduced. Secondly, if one side of the hip and thigh is sore due to cold in the hip and thigh, usually accompanied by aversion to cold and aggravation of soreness when cold is encountered, it can be treated by moxibustion therapy, infrared irradiation therapy and hot compress therapy. Through the warming effect of these treatments, the cold energy in the body is dispersed and the pain is relieved.
