Hi I am 23 and slightly overweight. I have had these symptoms for like 2 months now. Wheezing, tight chest and back, sweating, light headed. I am taking alot of asthma medecine. Symbicort, albuterol inhaler and nebulizer, montelukast and was doing methylprednisolone for asthma but none of this has helped. To make sure its asthma and nothing with my heart I have had 3 EKG's, a chest Xray, CT scan, Stress Test and multiple visits to the doctor. I have also had blood work. Along with this i do have bad anxiety but have a constant heaviness and wheeze. My question is based on the tests I have had if there was something wrong with my heart something would have shown up on a test somewhere right? They said there's no way it can be my heart based on the results I just wanna see if anyone has any other opinion. Also any ideas on how to help with my asthma which is what they suspect is causing all of the trouble? Also after I started the presnisolone ive had some light headedness and fuzzy vision is that normal?
