Ganglion / Wrist Bump. For it!

I have a small bump on my right hand wrist. Its size is similar to a small marble and this bump has been bothering me a lot from past 3 years. I am not able to do my gym workouts and am not even able to lift light weights. I have consulted 2 Orthopedics doctors. One of them suggested me that the bump is a Ganglion and gave me a steroid shot to reduce the pain. After taking the shot i was able to do proper workout for one month but again after one month my wrist started paining. So I consulted another Orthopedics doctor who suggested that its not a ganglion and has asked me to consult a hand specialist.But still i had taken another steroid shot from the second doctor and this time even the steroid shot didn't do it right. So now am really worried about my wrist and i do not really understand what should i do further. Can someone please explain me about what exactly my wrist bump consist of and if it is a ganglion then can anyone please recommend me the right solution/treatment for it
