I haven't been well since i have had my appendix out and basically i was in hospital last week again they couldnt find anything wrong?

Tincture of time: Often, an emergency operation is a big impact on your body, and even though the wounds are healing well, it is common to have a poor apetite and get fatigued easily for a number of weeks, sometimes months afterward. If you think something is wrong however, call your surgeon for an appointment. Hope this helps, and good luck. You'll come around.
