I suffer from lingual nerve damage and resultant paresthesia of my tongue, right side, from an injection of articaine 10 months ago. I know what you are going through... my symptoms are 10 - 30% improved, depending on the day. I can tell you what I am doing and what helped me the most. Every day I take Vit.B12 (5000mcg. sublingual methylcobalamin), Vit.B complete, Vit.C (4000mg), lecithin, and fish oil for Omega 3 EPA and DHA for nerve repair. I also take an antioxidant (Solgar Advanced). Therapy wise I use acupuncture for relief of pain and burning... and it does help. I treat myself because that is what I do professionally, however I highly recommed it for any nerve pain or repair situation. It's important to treat local points in and under the tongue itself, as well as distal points on the arms, hands, face, and even legs. Another technique that helped is hot salt water soaks... make some salt water (hot) and then wash your mouth out with it keeping it in the mouth (and touching the affected gums, tongue, etc.) for a couple of minutes, then spit it out. Do this 3 - 4 times in a row, it should help with the pain because of the hygroscopic effect of the solution... it will help to relieve inflammation including inflamed nerves. I also massage the area where my dentist injected me with my thumbs. This has also helped a bit. Someone is reporting good results using a micro-current device called the Alpha-Stim 100. Similar to a TENS unit but not the same... different wave forms. Just Google it. Good luck to you, me, and all who are injured. This injury is terrible, but time, and some therapy, will help in almost all cases.
