I'm starting to wonder if maybe I'm allergic to milk now, not just lactose intolerant. I had a slice of pizza earlier this week, 2 lactase pills & no problem. But tonight I had a casserole that had sour cream & shredded cheese, 2 lactase pills before meal, & 20 minutes after finishing I was having the worst abdominal cramping of my life... Or maybe I'm allergic to something completely different, I have no idea *sigh* I don't know if this is signs of an allergic reaction, since I'm taking antihistamines. My reactions usually involved all the other horrible symptoms as well as cramping, when I wasn't taking antihistamines.
