Any ideas please on what could cause this?

I'm having trouble lying on my right side for the past few nights - it feels a bit uncomfortable, slightly sore and bloated/swollen from under my rib cage and down to below my tummy button. I can't really put my finger on it - not a particular spot - just a general discomfort and general feeling of being bloated or having a swelling (but there doesn't seem to be anything there). Very weird. I am overweight so I guess it could just be that but I've not had it before. It's a mystery! Any thoughts much appreciated.
Thanks

I know this sounds ridiculous, but it could be constipation - I've had this type of pain before and that's what I put it down to anyway. Try lots of water, and take a laxative if you react ok to them (i don't) or eat a lot of allbran!

Keep an eye on it in case it is a grumbling appendix - if it gets very painful and the pain moves over to the the centre of your tum then it might be appendicitis.
