I had a dental malpractice in 2006 during root canal treatments that left me with permanent nerve damage TMJ headaches(migraines) and backaches daily. My Neurologist had me trying many drugs(anti-seizures anti-depressants Botox shots nerve block shots etc.) to try to alleviate the constant pain every single day some didnt work some had worse side effects or if they did help it only seemed for a few months and then my body adjusted. I have always been into natural remedies and tried a few things. I came across this wonderful website and this product Neuro-Chord. I am on my 4th bottle (dropped and smashed a almost full one I was bummed!) I wanted to give it a few months before giving a review but I can say that within the 1st few days of taking it my headaches were dramatically reduced the TMJ pain is still there but in no way as intense (Im still working on finding a remedy for that) I do also take on occasion Rhus Tox" homeopathic to help the TMJ but some days having to take so many for my level of Jawpain can be inconvenient! In addition I have also brought and tried the homeopathic "TMJ/Jaw pain formula" spray from this site which is very soothing on bad days. Unfortunately the weather can effect my headaches so once in a while I can still get a bad one but I have not had a migraine in quite sometime yay! I take Neuro-Chord 3 times a day and that seems to do the trick. I recommend this product to anyone who has everyday constant headaches its worth trying one bottle (which lasts me about a month). I know that there are different types of headaches and reasons we get them I just know it works for nerve damage headaches because that is my type. Before this incident I never suffered from real debilitating headaches at all. Its a little expensive but when I compare it to the Drs. Copay its worth it I was going every 6 weeks to get the nerve-block shots between the Botox shots and I have not been since back yet since my last Botox in Nov 2013! I have recommended it friends at work because they ask as they can see the real difference in me. :-)
