Hi I'm 42 and was diagnosed with pa a couple of months ago. On b12 injections on alternate days and waiting to see a neurologist. My question is though the intense fatigue - which I had been putting down to having a one year old - is gone I'm still intermittently getting aching pains, muscle twitching all over, pins and needles in feet mainly, weakness in arms and legs, pain and stiffness in legs in the morning and more besides. It's hard to get much information and my gp is not very knowledgeable. So I wait to see the specialist in 5 weeks. Is it normal - though I know there's nothing standard about pa - to only get intermittent relief even with 8 weeks of b12 loading dose on alternate days? I'm quite worried about this and worry something more sinister is going on though these symptoms seem to tally with what I've read about pa. Any advice would be welcome and thanks in advance.
