I gereral have problems whenever i do any vigorous cardio workout. Sometimes i get cramps and tightness in my calfs, but typically depends how hydrated i am and if i am breathing correctly. but the problem the concerns me the most is when i am conditioning and i get a sharp, shooting pain in the right side in my chest. Usually disapates in a few minutes but forces me to slow down. Also when running my feet tend to swell alittle and being to feel pain, usually goes away when i cool down alittle. Also i sometimes notice when my feet swell i might have a vein bulging alittle in my legs. occasionally, i have problems with fatique. Whenever i am conditioning for a sport, i have a hard time making progress in terms of being more in shape, when gets very annoying. This hasn't always been the case, it started in freshman year of highschool. Any suggestion would help. in case u need it
im 16, 5'10'', 165lbs, not a smoker, and have allergies.
