I feel for you....last June I went to bed one evening feeling absolutely fine, but as soon as I got out of bed the following morning for work I had an excrutiating pain in the left hand side of my buttock. I hobbled around the lounge trying to walk it off but it just got worse and I ended up getting undressed and back in to bed.
To cut a long story short, I had the paramedics come out and they said I must have pulled a muscle, they gave me some painkillers and left me to it......three hours later after writhing around the bed in agony and my left leg going numb I called an ambulance and a few hours later I was in hospital.
The doctor diagnosed Bursitis which was incorrect as subsequent visits to my GP and an MRI proved that I had a bulging disc in my back, this in turn was pushing against the nerve that runs down my left leg which left me on crutches and a virtual cripple for 2 and a half months.
I'd never been ill in my life (51 years) and to suddenly go from being perfectly healthy to bedridden within a few hours was totally sobering. At first due to the misdiagnosis I was hoping to be back at work within a couple of weeks, but in the end I was off work 2 and a half months and even that was too soon.......9 months later I still have a limp and a dull/tingle/pain in part of my leg even though I've had physio and been doing excercises.
I really do wish you luck.
