Hi Virgofish,
I have experienced RSD for the past 27 years and have been lucky enough during this time to experience remission. The unfortunate thing is that it keeps on coming back.
In relation to insect bites, I have been unfortunate to have been bitten by a number of insects; green ant, scorpian, spitfire caterpillars and a whitetail spider. These bites appeared to have dropped my body's immune system to such an extent that I had an episode of RSD come on. Mind you, this is what my husband and I believe, so far we have not had a doctor disagree with us yet.
From my experience, RSD can be brought on by a very minor injury. Anyway, I am thinking of you and sending you all my positive thoughts to you.
Oh by the way, just in case you are wondering, I have RSD in both shoulders, hands, fingers, wrists, right forearm, right elbow, right lower leg, right ankle, right foot and toes. This particular episode has been going onI always look at it this way, it could always be worse!
Catch ya later,
