Muscle Spasm
"Awful experience taking this for lower back. But this week I had a spasm in my neck. IBProfin was not working. I was so uncomfortable I took one pill. It did nothing except make me feel SO tired. I didn&#039;t even remember going to bed. The next day, I felt extremely lethargic, zombie-ish and depressed. It&#039;s an awful and pointless medication."
