I'm on holiday right now and away for another week. Just before I went I did something to my back through over-zealous pre-holiday exercising. It was sore - lower left back, just above my pelvis - but not agony. However, a week later it really is; the pain has travelled down my leg and when I stand up / sit down / fake my first few steps I have an excruciating shooting pain in my hip, behind my knee and in my calf. Is this Sciatica? It's getting worse and I don't know what to do! I've been doing yoga and stretching every day (told the instructor on the resort about it but not confident she's an expert) and had a sports massage. I've also got some mega ibuprofen to take the edge off (thank god for continental pharmacies who dish out the drugs so liberally): is there anything else I should be doing to get rid of it? Do you think this diagnosis sounds correct? I am ruining my family's holiday with my lack of mobility and shrieks of pain and I'm not having a ball myself to be honest; now how I imagined the longed-for summer holiday was going to go!
