I have tendonitis in my shoulders, how can i make it better?

Rest, NSAID, therapy: Depending of the severity of your injury/tendinitis, it may take some time to heal. Should give it some rest. Gentle range of motion exercise, and use of antiinfkammatory med such as motrin/aleve may help. You may need cortisone injection and/or physical therapy if severe. Must minimize/avoid activities that caused your trouble. Consult doc for eval. Good luck.

Many Possibilities: Prolotherapy typically by itself will cause ligaments to tighten up, usually due to scarring or fibrosis of the ligaments. However now prolotherapy is used to introduce new blood supply to the area and then many times following it with the prp and/or stem cells in the area can repair the tissue/ligaments by the hopes that the stem cells regenerate the same normal tissue type.
