The most common forms of arthritis are degenerative conditions without cure. Treatment focuses on minimizing pain and reducing the impact of the disease on your body. A key treatment for many arthritis patients is physical therapy.
Platelet-rich plasma (PRP) is an autonomic regenerative treatment technique, meaning that it’s derived from your own body tissue to help speed up natural healing. Useful for many musculoskeletal issues, PRP can help with your shoulder injury.
The largest and longest nerve in the body, the sciatic nerve is a common source of pain and other symptoms. Usually affecting just one side of the body at a time, sciatic nerve pain can be temporary or chronic.
