welcome to HCM..
its good you are taking medication .. but u should even take mucolyte or expectorants to relieve ur mucus ..and moreover as its already 3 wks u should also go fofr investigations like sputum test for AFB ,and blood tests and x-ray to rule out other lung diseases..
and earache and difficulty swallowing will be mostly due to blocked EUstachian tube
..take warm water with salt gargling and drink warm milk or water frequently to get relieved of ur earache .. it takes time for that .. or u can even consult ent doc as he wil explain u further process..
anyways better go for investigations ,..
