A year ago I was prescribed Alendronate 35mg, once a wk. After 2 months I develope a blister inside my mouth on my gum, it did not hurt or bother me. I later developed a blister on the outside of my mouth near my lips
. So i read insert which said to stop taking medicine if you get mouth sores. The blister inside my mouth never went away. Recently I get small blisters around my mouth, Atleast a week, I have 4 now and They bothers me. Do you have any idea what it making this happen to me? Please help!
