Since October 2018, I’ve had problems with my chest. Been in and out of doctors, was told I had a viral infection so was given antibiotics and steroid tablets. This has now cleared us but I have also been diagnosed with asthma. I no longer have a cough or breathlessness but constant discomfort in my left side of chest / armpit and sometimes upper arm and shoulder. I had a chest x ray, ecg test and blood tests done in which all came back clear. I tend to feel this more so when laying down or sitting upright, I try not to worry about it but I can’t help as it’s been almost 4 months now. I also feel like my heart beats harder than usual and sometimes faster. I also get cold hands/feet at times along with pins and needles type feeling. Any help or suggestions would be much appreciated. Thanks!
