I had one of these as well. Formed after I broke my wrist. Not sure if that was why it formed but I didn't have it before. It's dispeared and come back a few times. I think I smashed it riding dirtbikes a few years ago and it hasn't come back since
here is the Mayo's take on the cyst Aspiration In aspiration, your doctor drains the fluid from the cyst. To do so, your doctor applies a local anesthetic to the area above the cyst. Then, he or she punctures the cyst with a needle and removes the fluid from the base of the cyst with a syringe. Your doctor may recommend a steroid injection into the empty cyst after aspiration. This procedure can be done right in your doctor's office. After aspiration, as many as 60 percent of ganglion cysts may recur. If the cyst recurs, aspiration can be repeated. However, in some cases your doctor may recommend surgery to remove the cyst. http://www.mayoclinic.com/health/ganglion-cysts/DS00767/DSECTION=treatments-and-drugs
Looks like a cyst. Actually, just like one. I had a friend with a growth like that on her wrist and I had to say it was a bit disgusting. Especailly on a female.
He injects massive steroid needles directly into his hand while his gay sparring partner fellates him. Pretty obvious.
Ah, now it all becomes clear! They figure if they somehow grow a cyst on Manny's hand, they'll have an out when they flunk a steroid test! Brilliant!
He wore Shane Mosley's boot that made him fight bad as a glove to spar with the guy that injected him with roids.
