An anecdote supporting the notion that even if the stitches don’t need to be removed by medical personnel, a visit to the doctor to allow stitches to be removed can allow other things to be checked on.
Mom cut herself somewhat severely between her index and middle fingers of her left hand. I took her to the Urgent Treatment Center, where they declared that she was bleeding profusely enough, and had cut herself deeply enough, that they wanted her to go the Emergency Room (at a particular hospital) so that if she’d nicked something serious, the experts would be available to perform the surgery.
So we drove across town. Eventually she was stitched up, bandaged, and given a referral to a hand surgeon.
Hand surgeon checked her out the next day, rebandaged her hand and told her to come back in a week or two.
When she went back, her stitches were removed, her range of motion was checked, and her doctor recommended that she walk down the hall to the physical therapy department and get some physical therapy. She was assured that the therapists kept appointments for the doctor’s patients, and so no appointment was needed. She went down the hall, got advice on exersizes, some “Thera-putty” (special Silly Putty) and scar treatment.
Between the physical therapist and the doctor she also got a lot of assurance that she hadn’t hurt a ligament in the original injury.
