Talk to General Physician on Multiple Problems

About 15 years ago, in the beginning it was just heartburn and anxiety, a doctor diagnosed GERD, started taking omeprazol and been taking on and off till today. About 5 years ago, started feeling breathless and dizzy after 10 minutes of talking and walking, still there today, then came along discomfort in the chest, now 6 months ago came along head tightness all the time and sometimes mild pain (except when i am asleep) along with all the previous symptoms. Lab report showed I am border line high on cholestrol, prediabetic (A1C at 5.8), mild fatty liver, low in Vit-D. I'm 69kg at 1.73m height (BMI is good). I was put on statin, that would cause headaches (i never experienced headached before taking statins). Took for about 3 weeks, no difference. I body train workout for almost 45 minutes, 5 days a week. Few days ago I started taking D3 k2 and omega 3 supplements. Sometime I feel really drained and noticed that after an induced burp, energy level gets a little better. I'm tired of this condition. Especially the persistent tightness in the head and dizziness. Please some one help.
