Hey there I am 28 yrs old and for the last month or so I have been struggling to breathe finally I made a dr appointment and I was given an inhaler to help with this problem I used the inhaler a few times the same day and it got worse so bad I went to the emergency room they ran all sorts of tests ekg, blood work to see if my enzymes of my heart were damaged, a chest x-ray and the whole time I was there they were monitoring my oxygen levels all of which came back normal with my oxygen levels 100% they did say my white blood cells were a little higher than normal but not high enough to be concerned about. They discharged me still short of breathe and still no answers. I did smoke for 9 yrs but I quit smoking in October because I started with this shortness of breathe and it seemed to help but now here lately it's back with a vengeance and I'm not sure what to do. The only other problem I have is every now and then I get what feels like a muscle spasm in my upper middle right side of my back, and I have been stuffed up and runny in my sinuses I took benadryl to see if it would help thinking maybe it was allergies but that didn't help either. I'm running out of ideas and I've tried breathing exercises which help sometimes but sometimes I just get very light headed and shaky also I tried breathing in steam with essential oil for stress in the water that helped once then made it worse the next time I tried it.. any thoughts or suggestions would greatly be appreciated.. I'm getting very irritable because of this and I just want to breathe normally again.. PLEASE HELP!!!!
