I thought I would do a general reply covering the questions raised.
Despite what I thought he has not had scans for pn, but 2 mri scans for severe lower back pain - diag. osteoarthritus - only advised to take paracet.
Back pain is now less severe except after heavy lifting!

He describes chronic numbness in hands and feet, but naturally very worried about that in feet as balance is affected. Occasional shooting pains in feet.

Ceased taking metformin 18 months ago after 6 years.

Dr told him that only control of diabetes 2 keeps np at current levels - ie no cure.

So I think that we should go down the Pain Management route and see what a Consultant feels - let's get past the GP!

Last has a blood test a few months ago, so is going to check if they tested for B12.

Again thank you and will keep you all in the loop with any news/further opinions.
