I have been having health problems for about 6 years and they cant find out what is wrong with me. I get pains in my arms, back , shoulders, chest, stomach and pains under and round my right side of my ribs. These pains at times last days and go away or last hrs and go away and its difficult to get good sleep.
i also had pains in my back, on the right hand side. but it was mainly sore in my tummy, in the middle,
very painful, i would become a different person when i had these pains. thankfully i had my gallbladder removed last year and since then, no problems!
you have to be careful if your pain is lasting days as you might have an obstruction. see your GP asap
