I agree it sounds like gall bladder. Get it checked out anyway hon and see what they say. On a seperate note, I know the neurofen plus is helping but do try to restrict how much you use and make sure you have it with food. You don't want a bleed in your tummy as well. I recently had a chap come through work who took a whole pack of neurofen plus in a 12 hour period to cope with a migrane... he ended up with a massive bleed in his gut and a 3 day hospital stay. Better to head to ED and get them to give you something stronger as well as investigate the cause of your pain. Sounds like you will need some sort of imaging done to work out what is going on.
