Jenni,
Aaack! Wow!

There is a known correlation between CRPs and ACE inhibitors. Maybe changing this med could make a difference for you.
ACE inhibitors increase bradykinin and other neuro peptides that contribute to neurogeniic inflammation. There are a couple of studies out there on this. The link was solid to cases of CRPS and not seen in other types of antihypertensives. Can you safely switch to something else??? Alpha blockers have the affect of downregulating adrenaline receptors which are implicated in neuropathic pain and also provide some partial sympathetic blockade orally. But really ANYTHING other than an ACE inhibitor would give you a better chance.
Ideas and tips - getting in the water is good for most everybody, omega 3s, Vit C, epsom salt soak or lotion, lidocaine cream and my latest trick....cough syrup. Yep cough syrup. Dextromethorphan is an NMDA antagonist like ketamine only not as strong and usually needs a high does or quinine to help absorption. But I figured what the heck, it's a cheap reasonably safe thing to try. For those of us who are sensitive to meds it just may help. I take the max adult dose before bed in a formula without any other OTC meds. Don't know if it's placebo but I have felt more comfortable lately.
