Good Morning John..
Thanks for the info and thumbs up..., but like my wine, so have to put up with the twinge...the PN started about 4 months after the Camino. I self diagnosed it and 2 drs failedto...then one of my sons just booked me into the Spire clinic in bath to see a neurosurgeon and sure enough I was right.

I have a daily routine of either spin class or sauna and plunge pool which I have been doing for years., and I have been a gym bunny since god was a boy which in later life has paid dividends and at 81 I am not giving up drinking but have cut back bit.
Why take Tadalafil every day even if you aren't getting layed? ...simple answer is induced diabetes in mice has had remarkable recovery studies using Tadalafil and since erectile dysfunction is all about lack of blood, the ED allows dilation of the arteries especially around the sciatic nerve allowing higher oxygen flow over the damages neurons., at least thats my take on it, its also totaly harmless at this dosage..add to that the cold water plunge pool that numbs the legs ., and right now its bloody freezing I can dangle my legs in for about 15 minutes but cant submerse as its just too cold, and that gives me a good head start for the rest of the day.....I am allowed up to 8 co-codamol tabs a day but rarely take more than 2 and thats at night when the brain deicides to stop producing endorphins then the bad boy try's to kick in.... Conclusion:- Its working but requires dedication to a routine that I have been doing for years even before PN , and not one for taking the medical proffesion at face value...hope this helps .
