Well, welcome to the forum here. I hope we can all offer some helpful advice for you.
I'm really sorry to hear of your problems. I hadn't realised golf was such dangerous game. I think that you do need to get back to your doctor and sort things out a bit more because if there are nerves affected by pressure from the disks things aren't going to get better and could get a lot worse. I' not sure you might like the various things that could be done to you including a neurological exam to determine just what has problems. However, I think you really have to make sure if there is anything that can be fixed and to make sure it doesn't get worse.
I ought to point out that whatever doctor you have there will be some embarrassment but you just have to leave that outside. The doctors and nurses have seen it all before, nothing is going to shock them and they just take it all in their stride. The important thing is to get an appointment with your doctor, leave your embarrassment at home and go and discuss the problems. If it cheers you up any, my regular cystoscopy appointment (flexible tube into bladder) sees me lying on the bed with my p*nis coming out from a paper field with three female nurses, the female urologist waiting to get on!
No time for embarrassment.
Please let us know how you get on.
