Hi My mother tested covid positive on 22 April and is still recovering. She has weakness and sometimes mild breathlessness. She is not able to work and feels tired. Sometimes she has pain in chest. We are giving her the medications given by doctor mucinac, ecoprin, zincovit, vitC, respirometer exercises. Her oxygen saturation is between 95-97 but sometimes it goes to 92-93 which increases immediately  to 96 after few deep breathing exercises. So how many days will it take to recover??...and what else we should do. Should I consult a pulmonologist or cardiologist ?? Please suggest
