Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query
I would suggest an
MRI of the thumb. The likely possibility is that you have managed to develop a vascular knob. Now this will take delicate maneuvering to release it. However to confirm the diagnosis, I would suggest an MRI first, and of course a visit to the orthopedician
I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further.
