I am a T2 diabetic small frame small build 110 lb. I have recently started taking Lantus at night and Humalog before meals. After about a month my stomach pain was unbearable. It began with chills at night, severe dry heaves, (unable to throw up due to reflux surgery) and diahhrea. My doctor said he thought I had a virus. I could not figure out what was going on. I usually gave myself shots in the upper stomach area, so I moved the shots to my legs with no improvement. I even tried Levemir, but after two days the pains came back. I stopped all shots and the pain and other symptoms went away. Is there an insulin that doest not cause stomach pain, chills, and vomiting?
