I'm 59 yrs. old & my skull changes shape & size all the time now. It didn't used to. It has gotten a lot higher up from the base of my neck & wider side to side. It changes all the time, even from day to day, for months now, both contracting & expanding in different areas. I have read about tapeworms getting started in the brain & wonder if that can cause this to happen & I read about abnormal proteins accumulating in the brain & if this can be symptoms of that. My left leg above the knee had an area that got covered up with what looked like mosquito bites while climbing up a boat ladder two years ago in the tropics.
