I've had RSD for five years and not once during that time have I gotten sick. No colds, no flus, none of the usual things that everyone gets now and again.
I do not have a super good immune system, or I didn't before I got sick. I didn't get sick all the time but if something was going around I often caught it. In the time I've had RSD I had a boyfriend who was constantly getting sick and even though I was kissing and hugging and being around him all the time I didn't get so much as a sniffle. I'm not good at washing my hands and I touch my face and bite my fingernails far too much (the merest scratch on my face usually gets a minor infection if I'm not super vigilent).
So, I'm grateful for this odd "no cold/flu" stretch, having the flu on top of this pain sounds like a hell I don't need to go through, but it seems so strange. I'm wondering if other people with RSD/CRPS have had a similar experience or if I'm just some oddball.
