I had a small hang nail that got infected and ended up swelling up my whole finger. At first I thought it would go away if I took care of it, but the infection kept spreading. My doctor gave me Amoxicilin which is safe for pregnancy. Your medication is also on the list. The thing is if your doctor felt it was necessary it probably is. You wouldn't want to risk the infection spreading to your blood stream and risk hurting your baby.

So even though I try to stay away from all meds while pregnant, I still listen to y doctor since he knows more than me.
