Since last few years during season change i face a lil breathing issue,which starts and goes away on it's own.Facing the same issue since last 2/3 days,also the upper centre of the chest feels a lil heavy,like it feels weird while breathing.Don't have fever,sore throat or any other flu symptoms. Started taking Grilinctus 3 days back as the same was suggested to me long back when i had gone to a doctor with this issue along with some other medicines(which i don't remember the name of).Have also got an Asthalin inhaler for emergency.Though i haven't really tried an inhaler ever before.This one also i haven't used yet.The breathing issue though still  there but seems to be bit better,this heaviness in chest is worrying me.Do i have asthma or is it some heart problem.I am more worried as due to the current situation it's difficult to find a doctor right away.Please suggest what should i do.
