hi zinnia. i'm glad that your pt is helping your rsd. pt helped me gain a little mobility back. as for the gabapentin, i totally understand how hard the side effects can be but after a few weeks they subsided for me. i have had rsd for over five long years now and started with about 100mg 4x daily of gababpetin. i am now unfortunately up to 600mg 4x daily. it still makes me foggy but helps me manage the burning electrical like and pain and swelling that rsd causes. gabapentin along with a strong pain killer help me the most with my constant rsd pain. but what works for one person doesn't always work for another. i hope that you find what helps you the most soon. take care.
