Yes I think you have parasites, but did you know they are opportunistic? you only have them if the 'soil' is good for them to multiply. Due to the fact that you have diabetes and kidney problems also I would say that you are in a weakened state. You will only remove them for the time being with the Wormwood , they will always come back till you strengthen your overall health. I have the Wormwood tincture and have had this problem, only after seeing a naturopath did I get rid of my worm problem and improve my health.
blessings also,
