There was noise about injections that showed improvement for PN. I'm not talking about steroids that help for a couple of weeks with sciatica. This was something else that involved ankle blocks. If you search ankle blocks you might read up on it. I did not give it much consideration as there was no people from this forum that stood on the rooftop and shouted it down the mountain. I don't know your take on pain management but the name is self explanatory. I had been driven into a corner by my pain and my Dr. TOLD me how to take the Hydrocodone 10-325. With the combination of the Hydro during the day and Ambien to induce blissfull sleep, I began to be less depressed. I as well as anyone needs time for this geologically slow process of healing. As for being under the threat of random drug testing, I believe that an RX for whatever shows up in your blood would be sufficient to keep you out of the user category. I got off the Hydro after about 6 or 8 mo and didn't have much trouble. I'm having a little more trouble getting off the Ambien. I reserve the right to take it back up as my sleep these days is hit or miss. I believe that your body needs a minimum of 5 hrs straight sleep for healing. I did have a better time after I started the Ambien. Long story shorter, do what you need to do to get to the next day because time combined with nutrition and excercize and rest will all be needed. Good Luck, Ken in Texas.
