Since your upper back and leg hurts so much, have you told your doctor? You NEED to so he can run an MRI. There could be something wrong with your discs in the spine, and if there is, he could prescribe pain meds. Plus he'd send you to a NEUROSURGEON to get an opinion.

so you NEED to tell your doctor about the back and leg pain!! Make SURE he knows how bad it is! You can't keep taking that OTC medication!!! Plus your Pregabaline isn't sufficient to ease that pain. You need an MRI with and without contrast material, so talk to him, ok? And do it soon.

God bless & let me know what happens, will you? Hugs, Lee
