last 30 yrs you have been smoking
and so your lungs are showing the problem..there are wide range of problems concerned with chronic smoking occurring in lungs..
but i still appreciate your effort in stopping this smoking habit which might help u in recovering from ur problem very soon..
anyways right now i can just suggest u to go regularly for follow ups as ur doc suggests and keep continuing no smoking in future too..
going a bit late for follow ups doesnt matter much and u can even go now for next follow up..take care..eat good diet full of vegetables non veg and fruits and even milk so that ur immunity builds and u recover soon..
all the best,,..
