I rang the surgery this morning, explained the situation to the receptionist, and had a call back from Dr Penny shortly after. She has suggested I take an extra gabapentin in the evening, as that is when the nerve pain is worst. If it is bad in the mornings, or if my back pain feels more nerve based than musculoskeletal, I should take an extra one with my morning dose as well, rather than taking extra tramadol unless I really need it. I can take an extra 300mg of gabapentin from tonight, and then increase the morning dose as well after 3 days. I’m booked in for a review with Dr Godwin on 30th October to see how things are and to decide what my ongoing dose should be.
