[|AI|]  Hi.... by what you quote I feel that you were son might be having a connective tissue disorder. The Rash and skin changes you are observing could be vasculitis or dermatological manifestation of the connective tissue disorder. Tummy cramps is another symptom which is suggestive of this disorder. If u were your pediatrician I would suggest getting a CBC, ESR, CRP and ANA done. I suggest you consult with your pediatrician regarding this and proceed further. Regards -
