Well there are problems/pathology where pain goes down in biceps because of problem in shoulder. You will need to provide more details like how did the pain start? and any fever, is the swelling visible from outside, what movements cause the pain, what is written in the mri report. So for all that evaluation we need to talk in detail . We need to see if the swelling is in joint / muscle / or ligaments !
