Ok Sophie you really have jinxed me! Now I hope this is just I lay funny but I can hardly walk today! Its VERY difficult to get up from chair or move my left leg going up the stairs for example because boy it HURTS!! Its sharp - between my hip & very top of theigh?!? I'm hobbling to walk its a horrid PULL feeling ... even tried the shop to see if it would go away and I must have looked an idiot hobbling up and down the street! Its just my left!!
