Sudden onset of muscular pain

Am i covered for a physiotherapy visit to deal with the sudden onset of muscle pain when walking? I've no idea what's caused it but it is winter here and slippery outside (i've had a couple of near misses). Not being able to walk for more than 15 min without pain is really putting a dampner on my holiday and ive 2 months more to go. If i am covered, is there a process i need to follow or do i need to visit a specific physio?
