My father is 64 years old .he was having severe shortness of breath so when we took scans we have been told like it's lung infection and asked to consult pulmonologist. So after consulting ,he s feeling up to 70 percentage better and still taking medicine and consulting also. But previously before meeting up a doctor first he will get ulcer in tongue and after two days days if it's gone, he will have shortness of breath .today again he s having mouth ulcer. Worried whether will he gave same issue or is this mouth ulcer is connected with shortness of breath? Can someone please help with this .he s taking pulmoclear, sompraz and bifilac capsules.
