I have had 2 steriod injections for a herniated disc at L5-S1. About a week after each one, I started having bad leg cramps at night for a week to 10 days. Every night, several times a night. My doctor says he cannot come up with a connection but twice seems too much to be a coincidence to me. Also had a day or 2 of bad leg itching with some welts around this same timeframe. Anybody else have anything like this happen and get an explanation as to why? Thanks.
