This is a very common question to the MEA information and support services
So here are my standard brief notes on sensory symptoms, including paraesthesiae/'pins and needles' sensations:
1 There are a number of neurological symptoms involving sensation - loss of sensation, increased sensitivity to touch/pain, unusual sensations/paraesthesiae/'pins and needles' - that can occur in ME/CFS. However, it is sometimes very difficult to know whether they are part of ME/CFS, or a sign of another medical problem
2 Other causes of the above sensory symptoms include vitamin B12 deficiency, diabetes, hypothyroidism, MGUS/monoclonal gammopathy of unknown significance - which can cause numbness or tingling in the hands and feet and balance problems, Sjogren's syndrome. The list goes on…..
They can also occur in anxiety and when people overbreathe/hyperventilate.

3 So it is important to properly investigate these symptoms, especially where they are more pronounced, or persistent, or have more unusual features
4 The investigation of sensory symptoms in ME/CFS is covered in more detail in the Investigation section of the MEA purple book:

If the problem continues, and your GP cannot provide a satisfactory explanation, I suggest you ask your GP if you could have a referral to a neurologist with an interest in ME/CFS - such as Dr Abhijit Chaudhuri at Queens Hospital, Romford, Essex (if you are in the UK)
