I Was At Th ER With My 10 Year Old

I was at th ER with my 10 year old son with the same symtoms on this pass Thanksgiving day. Now I'm having the same situation, like pain on ankles and feel swelling, paint on my wrist and arms like niddles pinch on feets and hands, also redness on both arms and both legs, pain on the low back head. They only told me that my sons has althrigia...I think can be something else, because I see the same simptoms on me now...
