Worst buy I've ever made

Over the past week I’ve slept less than i ever have. Mid back pain is unbearable. Tried every setting from 30-100. Mattress also sleeps hotter than even tempurpedic which i did not think was possible. I’ve never had mid back pain issues before so this has surprised me. I’ve suffered from low back pain for a while but that has not been an issue on the mattress. The only saving grace is that i found I sleep pretty well on the couch where I have had to move to every night.
