I can't speak about Bone marrow edema, but earlier this year I did suffer from "mouse elbow and shoulder", brought on from too much computer work. It does make cycling difficult. The pressure from leaning on the hand and the impact felt from the wheel to the handlebars was not comfortable.
I tried physical therapy at my HMO. She gave me the rubber bands to stretch etc. But it didn't make much of an impact.
What did work was acunpuncture and laser light therapy. I had 4-5 laser light therapy sessions and felt improvement within days. Acupuncture helped as well, including my lower back pain.
