I have a really bad pain in my side,what could it be?
Whenever i lay down to go to sleep i sleep on my right side,lately for about the last two weeks i've been waking up with a pain on my lower right side and the only way to get rid of it is to lay down on my stomach which isn't very comfy for me. Now for the last three days even if i lay on my left side it begins to hurt,not as bad but still slightly painful. Again i have to lay on my stomach. Today i took a nap and it happened again except now that i'm awake i still have pain yet it doesn't feel the same,it feels somewhat like a bruise being pushed slightly. Is it anything serious? I've talked to my Dr. and i can't get an appointment right now but id like to know if i have to go to the ER. Thank you.
