Ten days after the Chinese meal I'm still stiff and painful down my left side. I took an antihistamine on Sunday, then took a day off pills and then took a montelukast yesterday, just in case the pill was aggravating the problem. It's all made little difference. I'm bending with difficulty and cannot sleep on my right side. It does seem to be emanating from the left side. I've been into my book of symptoms and I don't think it can be the kidney. I think I know what it is - unpleasant but not malevolent, something in the gut. Maybe I should go and see the doctor. Maybe making a booking will make it go away, just like the wisdom tooth and the ear infection.
