I've been having some issues for a while now and I'm hoping you can help me out. Last year, during the first wave of covid, I had a fever and all the symptoms but never actually got tested. I just went to a nearby hospital, took some steroids and tablets, and then recovered. But ever since, for about nine months now, I've been dealing with this constant mucus coming from my lungs and throat through my mouth, and there's this stuck feeling and congestion in my chest. I've seen a lot of doctors and gone through all sorts of tests like blood, urine, X-Ray, ECG, and even a hologram scan, but they all say everything is fine. I'm still really struggling with these issues. Any ideas what might be going on?

if tests are normal need not worry, start taking some cough syrup ,drink hot water
