I recently started steet bike riding and training for a 70 mile ride. I am new to street biking and love it! I did get my doctors permission to start riding. I have been riding for two months, four times a week with no real problems.My only issue Is that I get extremely out of breath when going uphill, even a small incline, and definite chest pain...doesn t really happen on flat surfaces though.I am on Toprol for tachycardia, which is totally controlled with meds, and a channel blocker for angina from lupus, and have had Pericarditis and pleurisy in the last year.This year I was very determined to fight back against my Lupus. .within reason, of course, and get healthy!I am up to about fifteen miles on flat, regular surfaces, with just some minor chest pain, which I am used to and unconcerned about. I figure something somewhere in my chest area is inflamed from Lupus and just causing annoying pain.Tonight, however, seemed different. I tried a new route with small hills and inclines. I was extremely out of breath almost immediately and had crushing chest pain, I think due to the incline. When I would stop to rest, the pain would slow down alot. Do u think I just have to increase my tolerance for riding up inclines, and this is normal to be out of breath with angina like pain until I build up my tolerance or something I should get checked out? I kind of feel like anyone who is not in great cardio shape would have also been out of breath with chest pain riding up those hills. Do you agree this is normal? I don t want to overreact. My cardiologist has recently suggested a stress test. With all my other tests from Lupus, I m trying to be healthy and not over test. What do you think? T
