You are having herpes zoster
..also called shingle on face involving ear..right?
Now it is healing and the lesion on ear was having hard scab, but now it has fallen leaving scar.
So, I think your skin is now improving , but you have tingling and pain in affected area.
I think, you would have taken oral antiviral like acyclovir
to relive pain and tingling which occur after shingle lesions.
You may take pain killer like tramadol.
You may be improved after few weeks
I hope you got my answer.
