Hi the other day I twisted my knee getting up out of bed its not bruised or swollen but getting a numb feeling in my toes how long will it take toheal?

Wait for to six week. The perineal nerve runs along the outside of your knee and occasionally can be injuried with a twist. This can cause toe numbness. Another likely cause may be injury to a disc in your back. Are you having any back pain? In either instance wait about six weeks to see if the numbness stops. If it does not (or if it worsens) see a orthopedist or physiatrist for a formal evaluation.
