Thank you for your responses I didn't consider that it would be long covid related as well.

Yes it seems so, I suffer with a tight asthmatic chest after covid, I try exercising but this does not help. I seem to be allergic to wheat products, makes my nose run whenever I eat them and then the sinus headache from the face to the rear of my head, normally builds during the day. Mt specialist physician said it is all long COVID.

Yes I have. I had sinus before Covid but it was nothing that couldnt be controlled with meds. I now react to plants when season's change and do not get the infection cleared up before the next change in season. So it has become chronic and I just have sinus continously throughout the year. I also have Dry Eye Syndrome and cannot take anything which will dry my eyes out even more.
