I've been having this same pain for about 8 weeks now. It comes and goes. But it's just below my ribs on my left side and goes ino my back. It's been quite bad last night and today but isn't unbearable - not even to the point of taking pain killers. More a niggly pain, sometimes an ache which occasionally becomes quite sharp.
I'm otherwise fine I think.
I need to go to the doctors but as it comes and goes so often I keep putting it off. But any ideas on what it could be so I can be attempting to ease at home in the meantime?
