Are you using Lidoderm patches? I can use up to three and just stick them where it hurts the worst. That can vary from day to day. One day they may be stacked on the lower lumbar. The next it will be one on the lowest part of the lumbar and one on each "cheek". I found an OTC that works wonders for me. Surprise Surprise!!!! After putting on the patches and I find I have more real painful spots (the norm) I rub in a bunch of Duragesic Rub. Go figure. It's just menthol and Methyl Salicylate. For me, it works better than the capsacium products. I keep a tube in my purse and by the bed and rub it in as needed. It's great for spasm and even lowers some of the nerve pain. I asked my pharmacist how it could be so effective or was I going nutz. He said he had numerous serious back patients who swear by it. Best wishes and I pray you get some effective answers.
