I am sorry that you are going through such a crisis.
What you are experiencing is happening all over. If you are in Mid West USA this seems to be more prevalent, especially if near or in rural areas.
First, make sure your problems are not environmentally related. There could be industries near you, which may produce contaminants that will contribute to these types of symptoms. Household mold, toxins, etc., should be investigated. Property contamination is another. Are there any pets? Do they display health problems? Check your surroundings.
If these are worms, then typical worm medication (readily available) could be administered after advising your medical care people that you intend to do this (should you decide this route) I am not giving giving advise.
Some of the phenomenon you describe have been reported in cases that involve unusual infections. However, many people start to suspect unrelated and irrelevant things, because of panic.
My advise for now, is to go to the Morgellons forum, and see if what is being discussed there has a direct relationship to your own experiences.
Parasitic infection are indeed on the rise, but there are things you can do, and sometime your immune system can take care of things on it's own.
