I've been having a bit of back trouble over the last week - bit like an electric shock radiating out from just above my bum cheeks - that comes and goes and only lasts for seconds but I've also notice a weird sensation at the front and slightly to the left of my left shin! It feels a little like pins and needles but fuzzier - do you think the two could be connected ? ?
Had the same symptoms ten years ago. Did nothing about it for 6 months, as it gradually got worse. After several visits to the doctors and osteopaths I went private as I was now finding it difficult to walk. A scan revealed two slipped discs, which involved having a spinal decompression. Still suffering 10 years on.
So see a doctor asap, don't put it off like I did.
