Do whatever your doctor advises. Even if Regent required it, they would defer to a letter from your doctor stating that you should not get it.
I don't know where you are in SC but there are many places to get it there including NMB, Columbia, Charleston, and many choices if you are near Charlotte.
IMO, ask your doctor first. If they say NO WAY - get a letter. If they say you should get it then get it.
