sprained ankle

Hi doc  My problem is my ankle I sprained when climbing and falling off so my foot kind of bended inside and took part of my weight on it. It happened almost a month ago and the thing, ankle,is still bit swollen from both sides.. Doctor took only x-rays and made sure no bones were broken plus said that soft tissue -ligaments- propably were just badly strained but not fully broken off. I took first week with the sticks and few weeks after that with a aid of this ankle brace. No climbing or other sports in 3weeks. just walking after that. Now its quite ok to climb peacefully but for example running, massive heelhooks etc. are no option. Do you think the healing process is taking too long and am I slowly destroying my ligaments/foot by not waiting and resting the bastard enough? Doctor also said that sports are OK, as long as "I can take the pain".. :D  Many thanks!
