Sutures are used to approximate tissues together for better healing.
Once the tissues heal, sutures can be removed. Sometimes wound healing is delaye and sutures need to remain till they do.
i am not a surgeon but i think that the muscles are usually sutured with non-absorbable sutures and the tissues under the skin are sutured with absorbable suture material (body has ability to absorb it) and the skin one or the other but usually with non-absorbable material.
Sometimes, non-absorbable sutures in the muscle can find their way to the subcutaneous tissue and can irritate the skin and the subcutaneous tissues. Sometimes, the irritation continues till either the sutures are removed by the doctor or the body succeeds in expulsion of the suture material.
You were right, the thing that you removed was indeed a suture and if in fact you still have some of those sutures left, your body might try to get rid of them with resultant inflammation till they are removed one way or the other.
So, it is a good idea to see your doctor for him to decide whether you need all the other remaining sutures removed or not.
