<s>[INST] Hello, i have been having some pain in my lower right arm for a couple of days now but felt it tightening and loss of power, i cannot rotate my wrist or elbow and it is very painful. I have hypermobility syndrome could i have a dislocation.  Kind regards yvonne [/INST] Hello,I do not think you have a dislocation. Usually, this happens after a high energy impact such as a fall or car accident. If so you cannot move the elbow or arm and it is very painful. I think you may have a lateral epicondylitis (tennis elbow) or extensor tendinitis which is overuse syndromes from your work or sport (tennis).The treatment of these syndromes is easy and simple. Avoid for few weeks using much the right arm. Wrap it with elastic bandage or tennis elbow strap, take Ibuprofen pills. It will be okay after the first week.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Mahmmad Gamal </s>
