I had an injury once and it took 3 months to recover fully. However, I think it depends on the severity of the injury at hand. I think a severe injury to the ankle can take 4 months to heal but I'm not a medical professional so I'm just estimating here. Best wishes to your friend, it sucks waiting around to engage in sports hobbies after an injury.
That's about the time frame I was thinking too! She really wants to get back on the court but it's been almost two weeks and there is still a little swelling and definitely a bruise so I told her no
Thanks for your reply!
