My dad 75 year's age, having asthama from past 40 year's,. He is having leg swelling from three day's, he had cold and flu week back for that he took treatment, after consulting local doctor he is out of fever but having mouth ulcer. Again we consulted for second opinion, doctor told he is having breathing issue, there might be a chance of lung infection due to that he is having mouth ulcer, they asked me to take my dad to multi specialty hospital and do check off and my dad is not having any diabetes and he feels like going to urination every one hour, Please suggest me the medications and specialist to consult in bangalore,  actually my village 70 km from bangalore.
