"i am happy with the voltaren gel. i have had 4 operations on my back. i have had metal put into my back to correct the bone structure and then had the metal taken out about 4 years later. i have been on the gel for about one year off and on as needed. it helps bring down the pain i experience on a bad day. it takes a little while to work but it gets me to sleep at night when the pain is really bad. i have degenerative joint/disc disease and also problems with my periformus muscle and this gel helps bring down the pain. i recommend it and only need to use it 2x a day as per the directions. i have made the mistake of using more than prescribed and found problems when i use too much so follow the directions."
