Medical guys in here..
I got sick around March/April.. Had malaria and then I was diagnosed of muscle spasm in my tummy as there was a draw back feeling in my tummy whenever I breathe.. I wasn't coughing neither sneezing through out this period.. After few weeks I started fee pain around my abs whenever I tried breathing, doctors clinical diagnosis came back as lobar pneumonia.. Got treatment for that and it left. All of a sudden chest pain started, painful ones, I told my family I think I g covid but it wasn't looking like they gon believe cos for months no one was sick aside myself. I went to a doctor and he said I had Costobronchitis.. Got drugs and the pain left and came back again. Right now I'm having a hot sensation feeling from my back to my chest and my chest feels heavy. Chest tightness.. My family has completely ruled out this being covid cos they think it's been months and I'm still alive and no one has been sick at home.. Could they all be asymptomatic for 4 months plus? I called Ncdc and they agreed to the doctor's claim of Costobronchitis.. Thanks as I await your responses

Is it possible to be asymptomatic for months(3)
