They can also help with pain in general since they work on the NMDA receptors.

There is one other drug that works on Allodynia.

Called Neurotropiin. It's been out in Japan over 30 years and testing in NIH for 10 years.

I spoke to someone who has CRPS and she said it reduced allodinya by 40 percent.

I tried to apply for trial but you need to have CRPS.
