I am a 62 year old male. Recent results of physical indicate all ok except for "severe" disc dessication in lower back. I do feel like my back's been beaten with a bat when I get up in the a.m. but am fine after a few minutes. Have been saving for a new tri bike and was ready to get fitted, but wonder if the bike riding will make matters worse. I didn't really ask my doctor directly, probably for fear of the answer. Anyone had similar experience who can offer advice?
