As above, is it still lame? Anti-inflamatory will help if so. We had a ewe with strike in her back foot back in August, brought her in for 10-14 days with a friend and after we sorted the maggots she had Alamycin LA and metacam every 3 days for the first week, sprayed the foot every day with blue spray which dried it up nicely, she went back out and has been fine since. Didn't trim anything but just made sure it was completely dried up and not smelling anymore before she went back out.
