John, go see the quack. A box of tabs,2 or 3 times a day for a week or so and you'll be fine,i reckon. Cortisone is a last resort. You'll be offered physio first. I can go on it's own. I was sent home with a leaflet last night. Apparently it's common if you don't work out much. If wfp'ing for 5 hours a day aint workin out,i don't know what is,lol
