Welcome to Neuro Talk. I hope others will be able to help you with your question. Medicines work differently for every single person. If this works for you to reduce your pain. I would tell the doc. that very thing, and take the medication. If I were getting 100% relief, I would take a sugar pill! Pain in hard to deal with in all respects. I also seek those things which helps my own pain. take care, and glad to have you at Neruo Talk. ginnie
