Sore Throat with mild cough and Phlegm.

2 months back I had blood in my saliva sometimes when i split, then also had indigestion with stomach burn, gingivitis another problem. I consulted ENT, he said it is mild infection and gave me Augmentin 625 along with Combiflam and Pantodac tablet for 5 days. Blood is saliva went off. Again after 2 weeks had same indigestion problem , stomach burn etc. Then i experienced irritation in throat , difficulty in swallowing, a sound feeling when i swallow saliva. Then dr asked me to take Atarax. I took it for 2 days and had itching palm problem and shrinking palm skins. After his suggestion, i stopped it and he asked me to take Zifi 200, Sinarest and Grilinctus syrup for 5 days. Irritation in throat went of , even that swallowing trouble but still i am having dry cough, continuous phlegm and sometimes strange feeling in throat. Please let me know what it could be. ? Is it anxiety as I had before or else is this really happening coz of other health issues. Whom should i consult ??
