hi..thanks for your query!
From what you have mentioned, you may be suffering from an eczematous disorder in the fore head and neck areas. I do not think Botox
has anything to do with it.It might have ,at the most, caused a bruise
in the injected points.But that should not produce the features you mention or stay this long.
As for eczematous patches, you should take oral anti-allergic medications daily for a week and apply a mild topical steroid
once daily for a week again.Emollients should be applied along with and the patch should not be left to dry .
