Hello, I am on the HCG diet...0.125ml SC a day. Last thre days, I have had a vague left sided chest discomfort, a little squeeze. Yes I have HTN...bvery well controlled on diovan HCT. I take welbutrin, potassium Mg, Ca++, MVI, and 1/2 a tab of phertermine 37.5 a day. What do you think? ck BP, ck EKG, Hold off on the phentermine...if it stops its the phertermine. If not hold the HCG...if it stopps then it was the HCG? I am a physician in denial...LOL
