Hi. I am a medical doctor. There is basically 2 types of Raynaud's: Primary (inhereted through the genes) and Secondary (due to another medical problem) i take it you have Primary Raynauds due to ur young age and i guess u already have been to a doctor. Well there is no real treatment for this condition, its basically just a different physiological response your body has towards a cold stimulation. Excercise is very good for you, stay away from smoking (very very important) and if it really bothers you, u can get a calciam channel blocker pill (called nifedipine) from your house doctor (some research studies have shown that it helps), drinking aspirin 1/2 tablet a day is also good you when u get older. You can also try omega fatty acid supplements (which is in fish). Hope it helps. Dont worry i hav a lot of patients with that condition...its not goin to harm you, just stay away from smoking.
