Regarding Chest pain. I be worried?

It's been already more than 2 and half months after covid recovery but sometimes I still feel Chest pain, earlier was diagnosed covid positive and hospitalized for five days with Mild ARDS, Type 1 respiratory failure this was mentioned in the discharge diagnosis, Now it's been more than 2 and half months Sometimes I feel chest pain and excessive runny nose, sometimes little fatigue and I don't have fever above 98 degrees, My Spo2 is 99% most of the time and CBC, D-DIMER and CRP level are normal too.. Few days back I had symptoms of cold like excessive runny nose and headache.. The chest pain is usually mild with burning and sharp.. Now I have runny nose, sometimes phlegm.. should I be worried??
