Do I have covid or is it some underlying condition?

I have a history of anxiety and wheezing from smoking. My very close friend who i hang around alot tested positive for covid. So my symptoms (if you call them symptoms) started back 3 weeks ago. I have had no fever (if i did it was very minor or went away quickly), did not cough.

3 weeks ago, i felt a reduction in my breath span, which was on and off. I just want to mention, I also am susceptible to anxiety attacks, which are manageable to function while be anxious. Fast forward 1.5 weeks, I started feeling a real reduction in my breath span, which was not much of a concern has a had a large breath span before. I felt temporary and intermittent slight burning and chills in my chest for 1-2 days and they went away. Few days later I had rib pain, my dad told me it could be some form of rheumatoid affecting the musculoskeletal of my intercoastal ribs. It would hurt every so often when i breathe, cramping etc, but this also went away in a few days.

Now fast forward 2.5 weeks. I feel tingling sometimes in my arm, happened twice and right now. My lungs are frequently taking turns being decongested. One lung will be easier to breath through and the other lung harder to breath through, but it would switch depending after exercise or waking up. I experienced lost of taste two times this one day, but each time i lost my taste, i recovered it within 10 minutes. I never lost my taste again. I also have been burping very easily after eating food. Ive had a little rash on my right hand yesterday.

Right now, i taste some blood in my mucus, but it seems to be going away. However, I did feel some blood drip down to what i believe to be my stomach.

Should I be concerned about these erratic symptoms?

I find it strange my symptoms are so spread apart. usually loss of taste comes early but mine happened late. Also no fever and coughing, but my friend tested positive which makes me doubt. I have tingling my arm but it goes away. Any recommendations or thoughts?

Update: Just now when i stretched my side a little, i felt a resistence in where i think the clot has formed and is at. it seems to be at at rib 4-6 on my left lung. since i tasted the blood, ive noticed the joint of my left arms thumb felt a little numb with tingling
