I took that medication too but my doctor told me I had to wait up to 2 weeks for the medication to start working properly. I had to stop it by the 5th day because the
side effects were awful and that pill almost killed me.
As far as I know this medication (Mobic) is prescribed for arthritis.
For pain I took a muscle relaxer Flexeril and it worked since the first day I took it. In 2 days I was pain free in my neck, arms and shoulders after having non stop pain and numbness for months.
