Hi Linda,

Sorry you're having such a dismal time, I hope you can find something to give you some relief. HwRSD makes a good point. I'd try to find a replacement for the vicoden, which is an opioid, it often causes allodynia/hyperalgesia all by itself.

here's an extract from the really excellent article posted by Roz/Buckwheat which is at:

"Although opioids are the gold standard for treating acute pain, their use is highly controversial in CRPS. "We know that opioids cause hyperalgesia," said Harden. "If you have a drug that causes hyperalgesia and a disease that is characterized by hyperalgesia, how logical is it to use that drug in that disease?" Oaklander agreed that it was theoretically possible for opioids to worsen CRPS, but she said that this should not prevent physicians from prescribing opioids for certain patients who have CRPS. She did, however, caution that the lowest effective dose should be used. Some pain specialists advocate the use of methadone for the management of CRPS, according to Cruciani. Another possibility is an opioid in combination with an NMDA antagonist such as memantine (Namenda)."

You never know, just replacing that might help somewhat,
all the best
