I think the fact that they haven't rushed you in to the office or hospital is a good sign. Hoping for the best for you breh.Had my MRI last week and I'll be discussing the results with my primary doctor on Wednesday.
Usually Wrists and Feet are prime candidates for Ganglion Cysts a.k.a. Bible Cysts because you can smack them with a bible and flatten them.
If you got a flashlight, put it at one end of the bump, and see if the bump is translucent, if so, its fluid and its a ganglion cyst.
Be well.
