| At
a Pain Clinic in San Diego, a doctor prescribed me Cymbolta as a
replacement for Neurontin, which I was taking every 6 hours. He
said Cymbolta works on the nerves, too, though its main use is for
depression. He may have been experimenting on me, I don't know.
I was in a car accident and broke the femur of the same leg where
I had RSD (you couldn't really tell much by looking at it, as the
visual symptoms come and go). He refused to believe that I had RSD,
citing that the definition for CRPS now says that you have to show
grey nails and so on. I was surprised and disappointed in him, as
he is a young doctor in his 30's. I had to cut his dose down; though
he was planning to increase the pills taken each week. (Editor's note - RSD/CRPS cannot be diagnosed from just one secondary symptom. The primary symptom is extreme pain, generally reported at "burning pain". Diagnosis normally depends on that pain being accompanied by at least two out of a list of secondary symptoms) After a while I got off Cymbolta, because it was causing constipation. Anyway, back came the "buzz" on my formerly injured leg and then the other one started the same electrical type buzz. So I got back onto Neurontin and knocked off that pain. What I found out is that the Cymbolta does work on nerve pain, or whatever it is that is stinging near what feels like the skin level. I didn't like the sleep that Cymbolta knocked me into and if I cut it down, along came a bad headache. It may be worth somebody else with RSD trying it. It takes a couple weeks, so it says, to pull a person out of depression. Dorothea - California, USA |
