I am freaking out! I have a blister on my foot, and it hurts very bad! A couple of days ago, I popped it and clear fluid that was really sticky came out. It also feels like a bruise. It doesn't look like a bruise is there but it feels like there is one, and when I walk, it hurts. I have looked up blood blisters, but I do not think that is what kind of blister I have. Is this normal? What can I do about my problem?
