What are you eating for breakfast, lunch and your evening meal? I think cleansing and internal detoxification would be in order. You do should NOT give up or be really worried, I have seen many cases like yours improve significantly once the patient undertook cleansing. STOP eating meats for a few weeks, especially red meats, eat white meats, more vegetables and drink plenty of water. Try to avoid fried foods and especially processed foods, convenience foods, sweet foods, and any alcohol. What do you snack on?
I'd be interested to know of what your diet and lifestyle has been like the past several years.
