I have been experiencing breathing difficulties for a few years (which have recently worsened) yet still no formal diagnosis.
It began in 2005 with chest tightness on exertion and a feeling of not getting enough air into my lungs - after a while symptoms seemed to subside.
Then in 2011, I had a 'relapse' (along with other symptoms including joint pain, palpitations, fatigue, tinnitus, acid reflux, dry eyes - I experienced all these in 2005 too) - a chest X-ray revealed nothing and mild asthma was diagnosed and I was prescribed Salbutomol and Flixotide. All blood tests 'normal'.
Then again, in 2014, symptoms worsened and I started having left sided chest tightness and 'weakness' along with more palpitations, when walking uphill. I had a bunch of cardiology tests and these came back normal, apart from mild arterial calcification. Again, blood tests normal, apart from high ESR, which fluctuated over the years.
Last year, symptoms worsened again - left sided chest tightness, a feeling of not being able to get enough air into left lung, shoulder pain on taking a deep breathe - and I feel I have to constantly flare my nostrils to breathe 'properly'. Also had 2 mild chesty coughs in the past year - something which I never seemed to get in the past. I had another chest X-ray (again normal) and was referred to the respiratory team at Charring Cross hospital - I had Spirometry (normal) and Cardio Pulmonary Exercise Test - which revealed very low inflammation levels and ventricular bigemmini/ectopics. I was discharged and my GP has now referred me back to Cardiology for Echocardiogram and 24 Hour Holter.
I'm still really worried, as these symptoms feel very much pulmonary related and I feel something has been missed/not diagnosed. I still have all other symptoms like dry eyes, acid reflux, worsening joint stiffness. I feel like I'm at the end of my tether and am seeing my GP on Tuesday - any advice would be much appreciated!
