I'm a 24 year old female that has had my share of symptoms, all of which have never produced an explanation. I guess I'll just list the most recent events and see if maybe someone else can make some sense out of it. I had chest pain in the military for 5 years and they ran every possible test you could imagine and found nothing so they settled on anxiety and panic disorder. Fine but the medicines made me worse than before so I stopped taking them. I currently take something because I couldn't take the anger and depression anymore but it doesn't seem to give me problems. I have had over 60 UTI's and have had an irregular period all my life, which are manageable problems. I quit smoking last year and started chewing nicorette. 3 months later I started to notice a shortness of breath which one day led to a panic attack and a ride in an ambulance where they told me next time to talk myself out of it. Nice. Turns out I was allergic to Nicorette.Way to go doctors!! I smoke occasionally now but almost 1/4 of what I did before. Over the past three months I've gained 50 lbs for absolutely no reason so I went and had a physical thinking there must be something wrong with my thyroid or something to that effect. Nope. Nada. To top it all off I started to have the shortness of breath a couple days ago though not nearly as bad as it was with the Nicorette. I guess all in all I'm trying to make sure that all of these symptoms are just bad luck and not something crazy that a doctor is overlooking.
