depressed- alone and suffering chronic pain after kidney surgery

Im from Canada, originally from another country, I came here like an year ago to get my kidney surgery and then go back to my country. Since then my surgery fixed smaller kidney problem but left me in bigger mess chronic dull pain in my abdomen on that side, which never goes away, moving or sitting doesnt make difference to pain. All tests are coming normal, pain doctors, even physiotherapists cant give answer or help with pain.... Then worse is doctors dont believe me for this pain, so no pain meds, I just have to tolerate this pain all this time. Worst of all its almost getting 1 year since coming here alone and away from family, friends and relatives... it feels like my problems are never going to end...

I dont know in my case if I should just go back and live with my family or stay here and keep suffering like this in the hope that someday they can fix me. Either way i lose I guess . Dont know which route to take

I hate pain. I hate when something hurts and docs can't find a reason ( for them) and don't believe you. I too ( no to the same degree ) have flank pain. A dull ache. Wraps around you abdominal area then back just below the ribs.
I had a kidney infection took the sulfa drugs but I have RA and get remicade infusions ( messes with the immune system ) and still have pain and they did an ultra sound and they tell me " no news is good news" ha! I want to know why I am aching. Is it my kidney. Is it fibromyalgia or RA ? But i know my Primary care doc is starting to not believe me and my rheumy is starting to blame everything on fibromyalgia and kinda makes me feel like my pain is only in my head. I know your frustration.
