Diziness And Gastric Problem. Diziness?

Hi One and a half month ago,I suffered from shortness of breath.I consulted a general physician and started using Restyl ,Levolin puffs, Zincovit,Vitamin C and Pan tablets for 8 days. After few days I was suffering from dizziness and fluctuations in BP.I use Targit 40 mg for BP and Tonact TG for cholesterol which is my regular medicine before the problem occurred. Then I consulted another physician,he asked to stop all medicines and use Petril Beta for anxiety along with my regular medicine.After few days,chest tightness and no belching problem started.Then I consulted gastro Doc who prescribed Sompraz D and Eliwel for 15 days.At present, I am feeling slight dizziness only when I am at home. To which specialist should I consult for dizziness??
