I had campylobacter (food poisoning)6 months ago and since then i have had a front left ache that then started to hurt in my back at the same height. It hurts everyday and now my shoulder blade/arm/side aches everyday. I don't know if this could be connected to the food poisoning but i haven't felt right since. Could the ache/pain be coming from my stomach? Although i have just saw an osteopath who says a few of my left ribs are tight and hardly any movement.
