I have got myself in a complete state about it. Until 6 weeks ago I was very healthy, now I am a debilated wreck. I have a weird burning, tingling nerve type pain in my bum, sacrum, lower back and it goes down my outer leg. I have been to GP 4 times about this, firstly they said it was shingles, secondly - anxious, third time wait longer, 4th time blood tests - normal. I also have loose upset tummy everyday. I'm not sure if this is stress, related to my back or another weird thing. I feel generally unenergetic. I am going to work, looking after my kids 8,6,4 but I feel desperate to get some help for this problem as I feel so down and tired. It's going to ruin Christmas and the GPs (have seen 2) don't seem to want to help me. I'm convinced it something very serious and it dragging me down.
