Post discharge from hospital, I have developed symptoms like Chest pain & headache and for past 6 days, I have been experiencing breathlessness on and off throughout the day and even during sleep. Additionally, I am experiencing Nausea along with breathlessness. I have been monitoring my SPO2 levels, BP and PR. SPO2- 95-97 PR- 90-115 BP- around 105/68 I am currently on the following medicines : Rifagut 200 mg - thrice a day (I have IBS-D detected 2 yrs back) Doxofylline (1/2 tablet twice a day) Foloup CV 200 (1 tablet twice a day) Criz M - once a day Pantop D (40) - twice a day I have taken the above medicines for 2 days now.
