Hi Everyone. This is my first posting. I was diagnosed with bilateral RSD in my feet about 3 years ago. Cannot identify any source of injury and my overall pain level was minor relative to other RSD patients. Soon after going on Lyrica - 200 mg/day (and nothing else), my left foot was almost pain free and my right foot went into remission. About 2 months ago, my R foot came out of remission and is not responding to higher doses of Lyrica (now up to 600 mg/day). I am waiting for a compounded cream to be delivered and insurance company denied a Rx for Neudexta. Pain level is still pretty low, again relative to other patients. I have moderate swelling and just started physical therapy. Therapist is using TENS unit and another electrical nerve stimulation (I don't know name). After two PT sessions, I am not at all feeling the current at maximum levels from either unit. I understand that my relatively minor RSD could get worse and/or spread. I am very curious why I am not feeling stimulus. My R foot is measuring about 4 1/2 cm larger than my L foot. While the swelling may be interfering with the current, I don't think it is enough to block it entirely. Any thoughts?
