The course of the disease is usually unnoticeable in the early stages. Only later do thickened bands of connective tissue and palpable nodules appear under the skin. The bending contracture of the fourth and fifth fingers is characteristic, i.e. the ring and the small fingers. There are problems with straightening the fingers during various activities, and with time straightening is no longer possible. The earlier we see a doctor, the better the prognosis and the possible full recovery.
