Dear Elmx01, Hello.
usually takes weeks to heal. Healing is quickened by giving rest both physical and cognitive.
In your case , you are having pain behind the eye along with irritability after 2 months i.e. about 8 weeks, it is advisable that you should have a CT scan
or a MRI
of head done. You should also consult a Neurophysician /Neurosurgeon for advice.
Hope my advice is helpful to you.
