Hi, thanks for the reply, I take Metformin 2 x 500mg daily, 1 x 75mg Aspirin and 1 x Propranolol 80mg daily, my BG levels have been fairly consistant and within my normal ranges throughout.

Following colour changes in my nail beds dependant on temperature my GP did say I had Raynaud's, but then another said I didn't and it was left at that.

The worst affects appear to be at night when I'm sleeping (waking with numb fingers etc), although this evening my arms feel like their burning and there have been plenty of shooting pains today...

Thanks for the advice and link to the magnesium thread, I'm off to have a look now,

Andy
