Question : Thank you.
I have worked out lifting weights for many years and just last night noticed a real assymetry in my right v my left biceps. My right side is muscular all the way from my elbow to my shoulder. However, my left upper arm has a lack of muscle/mass between my biceps and shoulder. My left biceps has a lump that moves from side to side when I press on it, similar to a lipoma I had on my back years ago. My left biceps also looks slightly deformed compared to my normal right biceps.
What do you think?

Please, send an image for review!

Detailed Answer:
Hi and thank you so much for this query.

Please, send and image for review. The nature of the lump would guide towards making a diagnosis of this condition. The fact that you had a lipoma before increases the chances that it could possible be a lipoma.

I look forward to reviewing the image and making more suggestions and recommendation on what the problem and possible solution is.
