Shortness of breath and chest tightness.

I'm really glad I stumbled on this page as most people seem to think that these symptoms I'm having are in my head or a spiritual problem.

I've been having shortness of breath and chest tightness for the past 4 months, at first it was scary, I thought it was my heart having issues, but after seeing a cardiologist and doing series of tests and checks including X-ray, ECG, Echo, a test to check for blood clots in the lungs and all which came out normal, I was placed on medication to treat Acid reflux and was given a Seretide Discus inhaler as well as solid tablet Sabutamol. I must also say that I've been on all sorts of medication withing this 4 month period and my body feels like it isn't mine anymore, I look like a complete shadow of myself and oh by the way the picture below was taken almost 6 months ago.

I can't say my symptoms have completely disappeared as some days are much better than others.

I did a complete Lipid profile check as well as a PCV check all came out normal.

This issue has cost me a lot of financial strain as well as affect the quality of my life generally.

I'm being advised to see a lung specialist to do a Pulmonary function test, in as much as I want to do this the cost implications is something I just can't afford at the moment plus I'm scared it might come back as normal as well, then what next?

It's quite scary living like this
