Re: they are back and big!!!!!!!!

These are probably the "mature" type which you never see because they are attached to certain areas [tissue organs] deep in the body. The fact you are seeing them suggests they are being disturbed and shedding from these areas. This is when they start to get angry.
I am not qualified to make any suggestions on how you should proceed [actually I am not medically qualified at all---I can only give personal opinions]
But, I would take this as an opportunity to 'go for the big guns' at this time.
