First of all,I wanted to thank all of you for your feedback. When I last went to my dentist he now gave me a prescription for SF 5000 Plus,with 1.1% Sodium Fluoride Prescription Dental Cream. It say's to use at bedtime,also not to eat,rinse or drink anything after using this for 1/2 hour. So far I can not tell if it has made a difference? I will post more when I know more. Also I cannot take Lyrica,it caused extreme swelling all over my body. I actually had to be hospitalized! This RSD is really starting to get to me! Also with all this going on,my Mom has less than 2-3 month's before she passes on from having Alzheimer's! She is at home with my Dad and lot's of care giver's. She is now on home hospice,she has a hospital bed set up in their dinning room. As of 4 days ago she is no longer taking any food's or liquid's! Please your prayer's would be helpfull! Love To all!
