My neck is very sore and tense (thanks HA) and I saw a way to massage your head and neck on Dr Oz. I took two tennis balls, put them in a sock, and put them on various parts of my neck and head while lying on the floor. I did this for about 45 minutes (which was a blessing, considering I have two very small kiddos) and i would say it hurt 90% of the time...in a good way. But I SLOWLY got up and I've been extremely nauseated since the moment I got up (30min ago) and still am. Anyone experienced this after a NECK massage??? The pressure was pretty heavy with the tennis balls.
