Other than this you appear to be having some vascular problems, such as
vasculitis, that could be compromising the blood flow.
Vasculitis can cause erectile dysfunction by compromising the blood flow to penis during erection. Vasculitis can also compromise the peristalsis, digestion and absorption from gut. With time the patient starts suffering from nutrional deficiencies, skin discoloration, cognitive problems, confusion etc. These conditions cause elevated ESR, CRP and positive pANCA.
