Sorry no link kept. But I definately remember seeing it.
As far as the corticosteroids, I agree. I had to take them for a long while before this return of HPPD for some fiberous growth in my abdomen. It has very bad side effects as said. Anxiety and more. When I read the side effects on the med sheet, it sounded like a description of a disease instead of a treatment. But I had to take them as they had no other treatment.
For the visual static, I had a bottle of prednisone for a short course from a doc but did not take them. For some, a two week stint may be worth the side effects.
What happened to spell check on the menu above????
