Hi mdstuker,
I’m sorry to hear about the issues you are having.
Unfortunately you haven’t provided any information about your body type and sleeping positions, the mattress you purchased (the specifics of all the layers), or the retailer/manufacturer you purchased from so there aren’t really any meaningful suggestions I can make without more information.
It sounds like your mattress may be too soft for you and if that’s the case there are some generic suggestions in post #4 here that may be helpful. I would also check the foundation or support system under your mattress as well because it could be part or all of the reason for some of the issues you are having (it may be worth trying the mattress on the floor to see if it makes any difference).
A picture along with more information would certainly be helpful.
