Bless you da69....right there with you to a degree. I had Covid last August and I am still battling fatigue, asthmatic bronchitis right now, pneumonia earlier in the summer & sinus infection that just went away. I have more joint pain than I did, Acid Reflux worsened and I have mucousy saliva in the back of my throat. I was told that Covid attacked my lungs & caused more autoimmune issues...not sure which ones I have right now as the rheumatologist is still not sure. The hot weather took a toll this summer with the high humidity causing asthmatic bronchitis. Some days are better than others, but, i am not where I was before Covid last year. I try to pace myself on the best day and not overdo or I will pay for it. I was using a rescue inhaler (Albuterol) which may be worth asking your doctor about and then I was put on a nebulizer 3 times a day this summer which has helped. Climbing steps is exhausting. I am praying for you right now. We will get through this! Hugs & Prayers....
