Peripheral neuralgia with Tegretol

Hi all ... has anyone had peripheral neuralgia as a side effect with Tegretol? It's happened when switching from 3x 200mg a day to 4x 200mg a day (2nd day of 4x a day) ... so not sure if it was left over from the 3x a day and it's got worse or whether it was a new thing with the higher dosage.

I'm not sure whether to go for 4x a day and stick it out or see if it still occurs on 3x a day. (Some TN pain on 3x a day, pretty much no pain on 4x a day). Or give up on Tegretol and go for Gabapentin instead (despite my dr swearing by Tegretol for TN)?

It's pretty painful, it's like having TN in my arms and hands - shooting pains and stabbing electric ones. It's making doing anything fairly difficult and also affecting my grip. No pain relief relieves it (much like the TN I guess!).

These symptoms were part of my getting off teg. I also had yellowing of the eyes and skin
W/in 30 days of the high dose. Neuromogist hadn’t taken blood at all by a year after commencing the med and now I think he was covering his neglect. This is why I advocate learning all about meds prior to taking them. This way you move forward with eyes wide open. Has your doc been good about taking blood to check liver function?
