<human>: Hi doctor,Im taking carbamazepine for severe neuralgia,but when I relax to go to sleep at night my arms feel like fire burning inside but ice cold to touch,I get Charlie horses in my palms,and I have chronic pin and needles in my hands.my question is is this a vitamin deficiency or a side effect of the medication, or is my neuralgia progressing?
<bot>: Hi, thanks for using Chat Doctor Neuralgia is pain along the distribution of one or more nerves due to change in structure and/or function of the nerves. There are a number of possible causes including: diabetes, trauma, chronic kidney disease, some infections such as herpes zoster and HIV, vitamin B 12 deficiencies or as a side effect of medications. Carbamazepine is not one of the medications known to cause neuralgia. The symptoms that you are describing could be as a result of progression of your illness, they may also be attributed to other causes of neuralgia. Since they are severe and causing you significant discomfort, you may want to consider visiting your doctor for an evaluation. If another cause can be found then the initiation of treatment to this specific condition may be helpful to you. I hope this helps
