Yesterday I attempted to demonstrate a cartwheel (3/4 times and the first time since I was a child probably). I then had to carry my six year old for quite some distance later in the day. Felt fine.
Woke up this morning and can hardly move my head without feeling like I'm being stabbed in the upper chest/top of spine/somewhere inside that area with sharp knives. Finding it difficult to cope.
I assume I've pulled a muscle or something. Please tell me I'll feel better by tomorrow???!!!
