I was seen at a pain clinic for a herniated disc and all the doctor wanted to do was give me injections into my back.he prescribed me hydrocodone 7.5 ,i had taken talwin nx in the past and it worked good so i mentioned it to the doctor (not to mention talwin nx is a schedule 4 and a lot less abusable) the doctor told me it had been banned in the United states? ?then I look it up on drugs. com and i can't find out if its still available in the United states or not? ?can u help me out on this subject?
