My brother is suffering from upper chest pain(especially innthe right side of chest). He had recovered from Covid on 3rd April and was tested negative on the same date. He has developed the  pain described above from today morning(22 April,2021). He has pain while breathing, and due to that his breathing is becoming tough. Measured oxygen and pulse using Oximeter , the reading is stable ,i.e Oxygen levels ~ 95-98 Pulse level ~ 57-80. As the hospitals are filled with Covid patients we are scared to go to.hospital but still scared whether there is some damage or not. He is also eating a painkiller for his teeth ache since a few days too. Please advise us for the same
