It's horrible for her going through such pain with them especially as she is still quite young at 12 years old.
I was going to suggest the pill but I think at 12 that maybe it's too much too soon if that makes sense? It's a pity because it does ease the pain so much.. I really feel for her going through this at such a young age as I would be in tears with the pain, was like someone was slicing my belly up :(
My mam used to get quite upset when she would see me so bad as she never got pain at all!! I know it's not cold out this time of year but a hot water bottle does ease the pain too.
