according to chinese medicine, the right side of the body is related to the liver, and i have read that the right shoulder area is definitely related to the liver. is it sharp pain?
if it's sharp pain, there is no way that i can know for sure, but i will make a guess since you might not be able to get ahold of anyone right now, i would guess that you might have something stuck in one of your bile ducts. you could try a castor oil pack if you have the ingredients for that, or i have read others say that drinking Epsom Salts
helps clear up post-flush congestion. julia chang always says to make sure you have coptis and curcuma around during a flush incase something gets stuck. too late now if you don't already have it, but if you do, that might take care of the pain. if you don't have anything mentioned above, you could try drinking hot tea with vinegar or lemon juice in it, as my chinese friend always told me that that makes the liver decongest. coffee enemas
are another thing that could help. they make the liver decongest and are good for relieving pain.
whatever you do, good luck.
