YES, go to the doctor or ER, don't play games
Yes, 22 year olds do have heart attacks and they do have ruptured or torn aortas that would cause shortness of breath. You would not be considered a Drama Queen with these symptoms. Go to the DR or ER, better safe than sorry esp. at your very young age.
CFIDS and FM have all sorts of odd symptoms that mimic other diseases and conditions. That's the big problem with CFIDS. We and the doctors have a hard time teasing out CFIDS from another disease/condition. YOU can NOT tease medical things out but the doctor(s) should be able to.
It could be something as simple as a nerve that is pinched and the breathing does come with CFIDS (I have it often) or it could be a heart attack. Never, never let any doctor say to you that you are too young to have anything - you are not too young to have a heart attack, torn/ruptured aorta, cancer, stroke or anything that is more commonly seen in older folks. The fact that you are thin means nothing.
I knew a 19 year old girl who died in her sleep from a stroke. They think it was from birth control pills. Apparently she was not too young to die from a stroke. My GI doctor told me a sad story about a young lady who just graduated from medical school and was having GI problems. She went to her family doctor who told her it was stress and that she was too young for colon cancer. My GI doctor took a look and almost fell on the floor. The girl had full blown colon cancer at age 24. She died from it and all because some idiot doctor told her she was too young to have colon cancer and she believed him.
You are NOT too young for really anything. I have been told many times that doctors and the ER people would rather see you and you not have major problems than for you to dismiss the problems and not go to the DR/ER and then get worse or die. That's from THEIR mouths.
Have them check your lungs and heart. Heart esp. given the shortness of breath. Ask them to cheeck the aorta. Really, ask them to take a good hard look at your heart generally. You may have a tiny hole that is causing problems. Or you may have any number of other cardiac issues causing problems that you are not aware of. Check that heart out really good. INSIST they pay attention to your heart and not dismiss you as having Mitral Valve Prolapse or some other typical heart issue. It may well be MVP but the tingling in the arm doesn't usually go with MVP, just the odd feeling and shortness of breath. Never allow a doctor or the ER people to dismiss you due to your young age and thiness.
My internist had a young woman who could not breath for two weeks. She went to the pulm doctor and they gave her antibiotics and still she had shortness of breath. She called him, barely able to speak, and he told her to run to the ER. When she got there the ER docs called him and he barked at them that she prob. had a torn aorta. Well, she was short and did not fit the pattern for Connective Tissue disorders (Marfans/EDS) where the aorta will rupture without warning or start to tear and can be caught. He fought with them over the phone and in the end, after now THREE WEEKS she did have a torn aorta. They operated and she took a long time to recover. She prob. did not die as she should have because of the low circulating blood flow in CFIDS.
GO TO THE DOCTOR OR BETTER YET, THE EMERGENCY ROOM NOW!!!!! YOU ARE NOT TOO YOUNG FOR ANYTHING TO HAPPEN.
UPDATE US AFTER YOU HAVE GONE TO THE DR/ER PLEASE.
