Helicobacter pylori infection.

My first time infection was in February for which doctor had given me ppi and on off oz tablets at that time I had diarrhea and coffee like vomit. I felt better for a month but then again in april I started having indigestion problem,stomach and peptic ulcers and burning sensation in stomach and in my food pipe. I had taken h pylori blood test for which showed antibodies of h oylori in my blood. I consulted an online doctor who gave me ppi, antacid and clarithromycin and metranidazole which I took in May. Since May I don't feel my condition has cured yet. I am again having same problems. A feeling of nausea, kind of burning sensations in ankle, wrists, stomach and food pipe. I feel hotness without ac. I am unable to eat food properly. Even a little bit of spice causes me upper abdomen inflammation and discomfort. I burp too and food gets stuck in my food pipe. Please advice me what to do? Any experienced doctor who can cure my h pylori infection?
