Thank you both,

Shady 123 and Aussie 100 for your time in replying to my message.
Your interest is very much appreciated.
I am still taking one 300mg capsule three times a day and, for about a week or so, felt much better. However over the past three days my hands and feet are again feeling really sore and I find that I am even kicking off my slippers in the evening as they suddenly feel so 'restrictive'. Perhaps the arrival of the warmer weather has some influence, I don't know.
I am due a six monthly review soon and am awaiting an appointment with the neurology department.
There seems to be so many variations as to what may be the cause of such symptoms. From reading of your own experiences and researching the web it certainly is bewildering.
My very best wishes.
