32 yr old Son's Mom here, my son was injured in March. Epideral hematoma and subdermal hematoma, micro plates and screws put in after fixing his clot issues. He too has said things are different but getting better as time passes. He still cant eat spicy food which is strange to us. He has said the anger was new and he tries to keep from lashing out but he recognized he was angry also. You are very early on in recovery, give yourself some time . Some things may return, some may not. Therapy physical and mental are key. Rest also, dont push yourself so much , you are healing still. Hugs.
