Saw GP yesterday as I had suddenly developed crippling stomach pain (just below my ribcage) coupled with pain in my lower back and top of my legs. I was also vomiting and had diarrhoea. GP diagnosed a nasty tummy bug and prescribed co-codamol and anti-sickness tablets. Also said to keep an eye on the pain in case it migrated to the lower right (just in case of appendicitis) or if the symptoms were not improving.
24 hours later and I have stopped being sick but the pain has not subsided and is only eased with the co-codamol. Pain also seems to have moved down a bit but is not localized to the right hand side. Would you phone the GP back or just keep monitoring it?
