Very few conditions actually require a home visit by the doctors and it is usually better for both the Patient and the doctors for an assessment of a problem to be done on the surgery premises.
Home visits are only done when the medical condition actually prevents the patient coming to surgery and is not serious enough to warrant the advice to go straight to the hospital.
If you feel a visit to the doctor may be appropriate, however, please phone early in the morning to discuss your worries with a doctor.
