Many thanks guys for the info, will have a think.

On another note i had a massage in the hotel i'm staying in about to 28 ours ago. The massage pillow was pretty hard and i can still feel where the pillow touched at the front and back of my head.
I was laying for about 25 minutes on each side and there was a degree of motion up and down thanks to the massage but she was generally gentile.
I've essentially got a front and back headache which semi response to acetaminofen but not completely and is of course worse when i lay down.
Aside from this i have no other symptoms have presented so far. My main concern is have a re concussed myself? And should i seek medical attention?
The headache is not severe to point out and i was able to sleep last night. Also have stronger painkillers such as Zaldiar which i have yet to try out.

Any thoughts will be greatly appreciated.
