Thank you again for the information. My tingling doesn't last all day but does happen everyday serval times a day so i guess i have paresthesia. I also have had my thyroid testing except for free T3.

Today I got my results back from the gp and she said they are all fine.

B12 443pmol/L (162 - 811)
Red Cell Folate 1739 nmol/L (545 - 3370)
Vitamin D3 85nmol/L (50 - 300)
Ferritin 51ug/L (15 - 290)
Magnesium 0.9mmol/L (0.7 - 1.1)

When converting b12 I got 600pg/mL, so does that mean I don't have a deficiency as I read under 500 would suggest deficiency. Although another thing I noticed on one of the blood tests when I got home was a comment noting 'Mild Neutropenia' and when I did a quick search on the term b12 and folate deficiency came up as one of the causes which I found interesting but may not be relevant.
