Hi as some of you know last week I was suffering from DP/DR I found MY cure which was vitamin D however since then when ever I walk or stand up for long than a minute I get a strange prickly sensation in my back almost like sum1 is pricking me with lots of little needles! It doesn't hurt as such and a good scratch gets rid of it! But I'm also getting a numb thigh when I lay down on my front and also earlier whilst I was standing my thigh went numb...I've been getting tingling almost numb feelings in my hands whilst laying on my front as well...not to mention discomfort in my belly ribs and kidney area, I was told I was constipated a couple of weeks ago but I don't think that will relate to the prickly and numbness would it? I do spend a lot of time laid on my front on the sofa but I am terrified its something serious like MS/spinal cancer / kidney failur all sorts is flying through my mind and I keep having to pull myself away from DR google! Anyone experienced any of this ...an I just run down after my really bad week last week or should I be concerned?
