Had pain in shoulder for a few months. hurt to teach up or out & now have pain in bicep with a small lump thats sensitive to touch. what could this be?

Complex Joint: The shoulder is a complex joint, & many conditions/ injuries (rotator cuff injury, bursitits, tendonitis, labral pathology, etc).Can cause pain as described. The bicep pain coulld be something that developed secondary to any of the above, or the cause of pain altogether. I suggest a physician examine your shoulder to determine your best plan of care. http://drmarkgalland.com/category/shoulder/.

Biceps tenosynovitis: The most likely source of your pain and swelling is inflammation around the biceps tendon (tenosynovitis). This condition is typically associated with activity or sports related overload/overuse of the long head biceps tendon. Treatment typically consists of activity modification and/or physical therapy, anti-inflammatories, and occasionally a cortisone injection.
