It is important to have regular check-ups with your lymphoedema therapist or doctor, so that you can see what progress is being made. They will measure your arm or leg to monitor the effect of treatment.
You may find it helpful to keep your own progress chart. Progress may be slow, particularly at first, but there should be a noticeable improvement in the limb after a few weeks. If you are worried about any aspect of your treatment discuss it with your doctor, nurse or therapist.
