You may feel much like your normal self after a few days to a week of rest and recovery following endometrial ablation. That said, regardless of how good you feel, it's imperative that you follow your post-treatment instructions carefully.l Do not pull, push, or lift heavy objects for at least two weeks. To be fully recovered from endometrial ablation means that you've passed the time in which the risk of internal bleeding exists. This usually takes just two weeks, after which you may receive clearance from your doctor for all of your normal activities, including sexual intercourse.
