Right side chest pain while breathing.

I'm a 20 year old boy from Darjeeling, WB. It's been like 1 year I'm suffering from right side chest pain. Pain starts in the evening time and when I breathe there's sharp pain. Sometimes I feel the pain is in the bone area but when I take deep breaths I feel it a bit inside. It started after I got seriously ill after heavy fever and throat ache last year during the month of March... Went to the hospital and because of covid couldn't get a medical checkup. Doctors diagnosed from outside and prescribed some antibiotics. Though my infection cleared out but the pain remained. It's a sharp kind of pain and occurs almost daily as the day progresses towards night time. Sometimes I also experience headaches as well. Though it may not be related... I also have an oxymeter at home and the spo2 readings are completely normal... there's pain only in one spot towards the central-right side of the chest. And now it has started to worry me ...
