Generally, patients only need simple painkillers for the first few days after surgery. You should book a week off work in case you need it, but most patients say they feel like a fraud by the third or fourth day! If your job is office-based, it is often possible to return to work within a few days. However, picking up small children and driving should be avoided for the first fortnight and be wary of any sexual activity for at least the first week.
Moreover, strenuous activities such as running, horse-riding and heavy gym work should be avoided for up to six weeks. Saving your energy to heal the body post-surgery is the most sensible way to reduce the risk of complications.
