Last year first week of December i started having chest & back pains, burning nose and a tension headache...I got sinus medication but it did not help much. I eventually got to take a lab COVID test (it was a mouth swab) towards december month end and the results came back negative. today January 21. its been a month and I am still having a persistant tension headache which does not respond to pain medication, and i still have burning sensation in my nose plus chest and back pains. my doctor gave me more pain medication and GERD medication.
