Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
is a chronic disease with lots of secretions every time you get attack. You should see that you use medicines till you get complete relief,till all the secretions are expelled or dried up. Otherwise the remnant secretions may aggregate at the bottom of the lungs. These may cause pain after few such attacks.
The pain could be due to gastric irritation caused by a number of drugs, of course inevitable. It can be confirmed by gastroscopy. So i advise you to consult a gastro enterologist.
I also advise you to avoid spices, junk foods, and oily foods.
Wishing for a quick recovery. If you have any doubts you can approach H.C.M.
