Hi everybody, been looking in for quite some time and feeling pretty overwhelmed with the amount of information available here, great site! Diagnosed with idiopathic PN in march this year after my rheumy decided no arthritis and sent me to a neuro, previously on amitryptiline, co-codomol and arcoxia. Neuro changed meds to topomax instead of amitryptiline, GP added gabapentin when topomax not really helping, side effects from topomax too much after giving it 3 months so tapered off and now on 900mg gabapentin 3 times daily alongside other meds previously mentioned. Two weeks in and pain not reducing, soles of feet and palms bright red at night and heat sensitive, ankles swollen, brain fog slightly reduced but feeling extremely dumb at times, also fatigued and sleeping quite a lot. Any advice on medication appreciated. GP appointment next week and will ask for B12 levels to be checked, what is a good level for the UK? Thanks in advance for any replies.
