Joint lesion
Mainly include degenerative arthritis, rheumatoid arthritis, rheumatoid arthritis, gouty arthritis, bursitis, synovitis, cervical spondylopathy, lumbar spondylosis, scapulohumeral periarthritis, bone hyperplasia, femoral head necrosis, etc. |
Lactic acid accumulation
Too much lactic acid will make weakly alkaline body fluids acidic, affecting the smooth absorption of nutrients and oxygen by cells, and weakening the normal functions of cells. The muscles that accumulate lactic acid will contract, squeezing the blood vessels and poor blood flow, resulting in muscle soreness. |
External force trauma
Such as twisting, knocking, bumping, and damage to the soft tissues around the joints, muscles, tendons, ligaments, and joint capsules, these external trauma can cause pain. If the trauma force is large, the bones around the joints will be hurt, causing bone cracks, fractures, and joint pain. |
