I Have Only Been Taking This For About Two Months.

I have only been taking this for about two months. By mid night or two a.m. I have aching in my shoulders chest, stomach. The pain is agonizing and severe. Should I continue this or stop it for I while. In my upper G.I. Last week, they found a ulcer in the small intestine and and acid which I assume the piece between the small intestine and stomach was caused to have partially crushed over. Thanks Jerry Edwards
