MY SON NOW 25 WAS THEN 16 WAS ACTUALLY KNOCKED OUT SO HAD A ROUTINE/RULE*OUT HEAD TRAUMA DIAGNOSIS (SO TO SPEAK) PRAISE GOD! NO LIFE THREATENING INJURIES TO MY SONS BUT SCAN RESULTS SHOWED "LYTIC LESIONS OF THE CALVARIUM!" ARE THE RELATED ILLNESSES OR TOTALLY SEPARATE DISORDERS!" THANKS AND "HAVE A BLESSED DAY!"

hi appreciate you taking the time to respond and I really don't mean for this to sound ugly I really hope you don't take it that way I was just thinking charge 30 dollars to be paid for that one-line answer seems pretty vague I apologize but I was kinda hoping for more details and things to look out for with these illnesses at basically seems like a one line answer that anybody could have given me I was kinda hoping to get more details are things to look future and symptoms are other things that may come up I think that XXXXXXX vague answer than anybody could have told me but thank you I appreciate it I thought it was professional given professional advice and detailed information since we can't just randomly have access to call a specialist on the phone and ask them thank you for your time and have a blessed day
