pulled muscle in neck: healing?

Hey guys! I am on a great path with my weight loss. I've lost a total of 15 pounds in 6 weeks. I don't want to give up the gym for so many days (yesterday, today and maybe tomorrow) bc I pulled muscles in my neck while sleeping. It hurts really really bad and so far, over the counter meds are working. Anybody ever used Icy Hot for a sore neck or anything else that worked? Hot shower, heating pad and meds haven't done anything yet. Any suggestions?!
