If you are someone who suffers from recurrent boils in this area then do please go and see you GP because it may be that you need a cause of antibiotics and an antibacterial wash. If this is a recurrent problem then we often prescribe a longer course of antibiotics to try and break the cycle.
This is because a giardia infection interferes with digestion and inhibits absorption of nutrients from the diet. It can also damage the lining of the intestine. In fact, this particular parasite is at the root of many cases of chronic GI inflammation in dogs and cats.
Expected Duration. The worst symptoms of giardiasis typically last for five to seven days, as long as diagnosis and treatment is not delayed. Symptoms can take as long as several months to completely go away after treatment because the intestine needs to repair itself. It is common to be intolerant to milk and other dairy products that contain lactose for the first few months after a Giardia infection.
