Dr Sobia Wyne has a long list of possible causes for a patient's eye infection, and a woman who has had knee replacement surgery may have developed deep vein thrombosis.

A woman suffering from depression and anxiety thinks she is ready to come off her medication, and a mother of three encounters difficulties with her contraceptive implant.
