I have a pain in my lower back which I think is a trapped nerve, today I experienced dizziness for about 20 minutes and was also sick, I had tingliness down both arms and legs and also pain in my legs, I've had this pain in my back for about 9 or 10 months now and only now it seems to be getting worse, this was the first time I experienced dizziness which I think is related as I haven't been unwell in myself and it just suddenly came on whilst I was standing. I'd be very grateful if you could help me, thank you
