I have been having like shock type pains when )i think) he is trying to engage his head - or move down further....

sometimes its like a electric shock sometimes like a cramp .. i try to relax to let him do what he is trying to do .. but i find myself sort of clenching my muscles together and prehpas stopping him..

has anyone else felt this - not sure if we have nerves there that they press on or if something may be wrong with me ???????????????????????
