It is ultimately a decision for fraggle to make. There is a wide range of "itching like hell" and it may well be that some of the previously prescribed medications may be involved in the itching. What we know now is that fraggle HAS had some diagnoses and treatments by a licensed physician. It hasn't worked out yet.
Fraggle, while you are sorting out what to do next, smear some yogurt on your eyebrows. Let it dry. Rinse it out with fresh water only. After a few days of this, is the condition getting better or worse?
Monkeyboots, had there not already been some medical intervention, I would be closer to your perspective on this. But the truth is, the specialists make nearly the same number of guesses that the general pracitioners do and have a similar track record of being correct. They simply get paid more.
