Could be many things: Will suggest a thorough medical exam to exclude any organic causes to your symptoms. If all work up is normal including drug and toxicology screens, then see a psychiatrist for an assessment to see if mood disorder especially anxiety could be contributing to your symptoms. Good luck.

Anxiety?: Excluding all physical causes of the symptoms, as well as possible effects of medications or alcohol or illicit substances, possibility of anxiety disorder versus tension myositis syndrome (psychosomatic musculo-skeletal-nerve symptoms). Consult with your doctor to discuss tx options.
