As this is the first post in this section I can only go by my symptoms which I have collected over time.
Initially I was very short on breath doing the most mundane things, I didnt really notice this too much because I was on the computer most of the time (like now!) and didnt really do any exercise to speak of.
I was also overweight which didnt help, overtime I developed a tightness of my chest area and other symptoms which is beleived to be directly related to connective tissue disorder for example, Raynaud’s, Dry eyes, Rash’s of varing verocity.
