thank you for that advice, i mentioned it to my physio and he said to see gp - however since my first physio session on mon (5 days ago) both my legs have been freezing cold and numb, and excruciating pain pretty much all over my body :S i saw a stand in gp on wed and he sent me to have more blood tests as i have an abnormal swelling on my wrist too. my last fbc test came back with a slight abnormality,things seem to be slowly unravelling.
as for the patches, i need to see my current gp for those, but il be going back next week hopefully - after physio again on monday :O
