No surgical procedure is entirely risk free. Nor are there any guarantees. No matter how experienced the surgeon may be, there is always a small risk that the procedure will not be entirely successful, of that a compication, such as post-operative infection might occur. In such cases further surgical or medical intervention may be necessary, but this should be at no cost to the patient. Make sure the surgeon has comprehensiveinsurance, and will agree to cover the cost of any necessary follow-up surgery, before going ahead. Pain: It should be remembered that pain is very subjective and patients give differing reports after the same operation.
