After taking opioids and I thought tapering down,,my memory is so bad. I thought it was permandnt. Then I hurt my back so bad I thought I had to get help by pain medication. I took a low dose of opiods and felt like I did before I even got sick. I thought it could've caused some brain damage but I felt like the person before I ever got sick. No depression and a happy outlook on life I had not experienced in years. I have asked dr's and can't get an answer. Can you help?
