What's the "difference" between the foam and spray? Any benefit using one instead of the other?

The foam is typically recommended for broad application, across large muscle groups, and "massaged" in. The (metered) spray is typically recommended for quick, targeted application.

Does the foam work for neck pain and knee pain?

I use it for cramps in my feet and legs which is muscular. Neck and knee pain sounds joint related. Write the company directly and ask.

Does it work for menstrual cramps

Theraworx Relief has been proven to prevent & relieve muscle cramps in the legs & feet. There have not been any scientific studies on Theraworx Relief for other muscle groups or conditions like menstrual cramps, but it’s safe to use on any area of the body if you’d like to try.
