I've just started week 5 and for the last week I've had a lot of lower back pain around my left hip/buttock area with a numbness down my left leg. It started after I'd done an 8.5 mile walk with a back pack on last weekend. When I'm running I don't really notice the pain as much but it's there all the time otherwise.
The question is, do I carry on running or rest it? I really don't want to stop unless I have to as I'm scared that once I stop for a while I won't start again! Any recommendations?
