Thanks Kicker.

I saw the physio yesterday- he asked, "so you have a sore neck?"...
"ah no, i don't actually!" I said....

He said the joint dysfunction theory is NOT causing my problems.
Don't think I'll see that neuro again.

He came up with a theory though for my lower right arm tingling/numbness which is a 'sick' ulna nerve from a bee-sting I had when the sx started back in march.
BUT when I asked about the other leg/arm/left side sx he said he didn't know, but the leg stiffness/heavy /trouble walking i get after sometimes 20-40mins is muscle tiredness and me not being fit.....hmmmm. Some days I can walk way more than that without trouble.
And the neuralgia is stress....
