Hi Mama Mac,
I am on LDN (temp off for surgery & on pain meds now). I love it. It took 5 weeks for me to work and I know it can take months for it to really work. You start off slow 1.5 and work up. I was up to 3.0-4.5 day taking 2 pills in morning and 1 at night. It honestly got rid of a lot of the symptoms for me, especially in the mornings (that's why I moved my dose to twice daily to spread out the relief).
The burning pain was the biggest change. I can now get up in the morning and get to the bathroom without crawling. Another perk is I don't get sick anymore. Everyone else int he office has colds, sinus infections and I have stayed healthy (well other than the CRPS).
The ketamine infusion also reduced all the symptoms. I think together the LDN and Ketamine are helpful and I can't wait to get off these pain killers so I can get back on.
Good luck to you.
