At first, you may feel easily tired and find it hard to do some activities. This is to be expected and will improve with time. Unfortunately it is difficult to place a time scale on your recovery, as everyone improves at a different rate.
You will have to gradually increase your activity over the following days or weeks and initially, may need help from the nurses or the physiotherapist. You may feel frightened to do certain things, therefore discuss this with the ward staff and they can reassure you about what to expect from yourself during your recovery.
