My wife took Levaquin last week Friday and about 2 hours later she started experiencing severe burning pains starting at the core of her body and eminating outward. We've been to the ER twice and she was given pain shots which helps but as soon as the medication wears off the burning sensation returns. Her doctor gave her Percotte and told her it will eventually work itself out. This the fifth day with this problem and it hasn't gone away. Does anyone have any suggestions or advise how to resolve his problem? Please comment.
