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.
The most common manifestations of giardiasis are diarrhea and abdominal pain, particularly cramping; however, diarrhea is not invariable and occurs in 60% to 90% of patients. Other common manifestations include: 1  bloating, 2  nausea with or without vomiting, 3  malaise, and. 4  fatigue.
