Head to upper chest issue. Blurred.

I was a corad 5 with pneumonia in lungs and was recovered in last August 2021. Since then my health is not like before. I have weakness in my body and get tired with simple tasks. I still have chest pain.. got my ecg and 2d echo done n it's normal. My symptoms are shaking of my hands if you keenly observe and is evident while doing some tasks, head also tics or twitches or shakes (can't describe), on and off headache at the back of my eye brows, terrible nausea, at times my left or right ankle, left or right hand (while I wake up from sleep early morning and try to get some more sleep) or fingers twitch along my pulse (while I'm awake, working). I have these sounds in my neck throat while walking or taking stairs.. since, two days I'm having upper back back ache too. Eyes feel sore and painful wen I wake up and I feel heavy eyes with my vision blurred.. Thank God, I'm alive. I just don't know to reach out to which doctor for my symptoms. Please suggest and help 🙏
