I had to take cipro for 5 days and then flagyl for another 5 days due to a bacterial infection that was not going away. The only side effect i had was when taking the flagyl. I experienced some tingling in my hands but it went away. It has been a week since I have been off the medication and now I am experiencing severe dry tongue and a feeling that something is on the back of my tongue .Could this still be a side effect from the antibiotics?
