DaisyB you have given me a lightbulb moment. I was diagnosed with ME (now called CFS) in 2004. Numbness, pins and needles and intolerance to alcohol and extreme sensitivity to medication and other chemicals (toiletries, household products) is very common with the condition. I was diagnosed at the National ME Centre in Romford and the consultant advised me of these things.
Some years ago, when I attended a local ME/CFS clinic I had a bout of numbness and pins and needles and weakness in my legs and also in my hands. I was given an MRI and also nerve conduction tests which ruled out any other problem. I was referred to the CFS clinic physio where I was taught about pacing (which I am not very good at). Also the chronic illness psychologist who was brilliant.
When I hit the menopause I started getting symptoms similar to before I was diagnosed and I think hormonal fluctuations throw other body issues into confusion. it also sent my thyroid levels unstable (I also have Hashimoto's hypothyroidism).
I have shared this to offer you a little support and, perhaps, a ray of hope that your worrying symptoms are not anything more sinister and, CLKD, I have to disagree in light of the ME. Perhaps not stay in bed all day every day DaisyB but certainly be mindful of rest and pacing in light of the ME/CFS and to fight it only aggravates it as does stress and nervous tension. Best of luck and a gentle hug x
