The high monocyte count is indicative of an infection. It might be bacterial, or some other cause. Imo a good regimen to put yourself on is olive leaf extract, grapefruit seed extract, plenty of vitamin c, 30-50 mg a day of zinc, and a B complex vitamin with 25-50 mg of each. Your other symptoms indicate it might be a systemic candida infection. Mercury toxicity can cause candida to grow out of control. Olive leaf extract and grapefruit seed extract work against candida, bacterial infections, and parasites. I suggest that you start out with small dosages of these. Perhaps start with just the olive leaf extract and see if you get a strong reaction to it. If your infection is candida, then you may feel worse after taking it, as candida being killed release toxins into your body.
