Hi, I have recently moved to uk, after 10 days of reaching here, I started facing chest pain and burning, I have used pan 40 , gaviscon for 3 days but It did not went away, after 3 days mild fever started 37.8 to 38.2 around, I caled NHS here, they said it is covid symptoms and asked me to isolate and not to visit gp, after almost a week, chest pain almost gone, but feverish is there some time (37.8 around less than 38 always), also felt suffocatd fraction of seconds when I sit idle and watching movie/some program, when I observed my nose, I see there is some red color tissue grown and blocking air passage, later I got to know it is turbinate hypertrophy, using Ottrovin,it is reducing when i use ottrrovin, and feeling suffocated again after some time, now turbinate is not that red as intial but my feverish not going ( 12 th day from my first symptom) also have used paracetmol almost a week, now I discontinued. Here we don't have access to gp/Doctor, can you please advise what can i do.
