Thankyou Layla....much appreciated...l am trying , all hindered by pain....always had this pain radiating from hip down thigh ..pain radiating to knee ( at outside) and stiff into calf....physio said it may ?? Be a bursa or nerve pinching ?? But didn't seem unduly concerned....l have tried to walk unaided, but have this severe limp and cannot seem to straighten...but l walk straight with stick...he said it will all come right...we are nearly 9weeks !!!...any advice on that ??
