Too all those who suffer from nerve pain in this case dental.i a have been through the gauntlet in dental pain.i have rsd/crps full body for 12 years.i was electrocuted.my surgeon who performed 15 surgeries on me, him and another dr.stated all my nerves are in flamed.i have been in chronic pain for nearly 12 years.all the usual symptoms and syndromes of rsd.but some of the sensitive and severe pain is you guessed it my teeth.right now if i drink a cold glass of water my whole lt. Side of my mouth flairs up.it is a pain you can do nothing about.i have been too the dentist and specialists.i kept coming out worst than i went in so i stopped going.after they pulled one third of my teeth and charged me after insurance did not cover.i realized i was the dummy.anytime they have too cut or stitch its surgery.and bam their goes the price.ins.wont cover that.after breaking my wrist and having 5 pins and 8 tittanium screws placed in it and then electrocuted in the same wrist with the hardware still in i thought i had felt the worst of all pain.nothing topped going and getting a tooth extracted and having too put a stitch in it.the pain went too a ten after the novcaine wore off.percocet 7.5 did`nt touch it.i finally had too get a stronger med before it settled down.but i can truly sympathize with you guys and gals on nerve pain and your teeth ive been there,it is horrorible too say the least. Thank god for his strength or i would`nt have made it.god bless all,thomas
