Stomach Pain & Diziness. Please suggest!

I had GERD symptoms 1.5 year back. Prescribed with Rabcer-D and RD Vit for a month. Things went well after that. Recently 3 month back I had some spicy food out of home and had stomach pain, acidity, heart burn and vomit. Got medicine from DR and got well, Then after a 3-4 days keep on getting stomach pain in a regular interval. This time prescribed with Pantop-40 for 15 days but still stomach pains in left side some time, right side some time, and in middle some time still there, so I went to a Gastro Entrologist this time and he checked my stomach by pressing it and prescribed Neopride total for a month and told if things do not go well I may have to go for endoscopy. But still mild pain was persists. 4 days back I had sticky stool with little fresh blood attached to stool. Went to DR and prescribed with Terflox-oz for five days and he asked to take curd rice only. Things are going well but still filling dizziness and very weak. Please suggest
