Although not common, sensaory changes are a part of CBD. Ths University of California site also mentions it. Link
Her symptoms are very typical of CBD and this is almost certainly the cause. The sensory symptom of pain is also, as I mentioned, often present although an uncommon presentation of CBD and so this does not rule it out.
Some of the treatment options available for the pain which you should discuss with her doctor are: Exercise
: Exercise is the primary treatment in all cases. You need to exercise regularly for this. Anti-depressants
: antidepressants like tricyclic antidepressants can often help. Pain killers
: Pain killers like NSAIDS are the first choice of treatment. For chronic intractable pain, narcotic analgesics like Vicodin may be given. They can be combined with drugs like phenytoin, carbamazepine, or tricyclic antidepressants such as amitriptyline for very severe pain. Anti-seizure drugs
: Drugs like Tegretol can also help with this. TENS
: transcutaneous electrical nerve stimulation unit provies low voltage electrical current which interrupts the pain signals. It can be applied permanently.
You should discus these options with her doctor for pain relief.
