My husband has suffered with CVID for many years. He is now back on gammaglobulin which the doctors feel may help his polyarthritis (which cannot be properly diagnosed, as he has no antibodies). He also suffers from a constant rapid pulse, and cold sweats even in cool weather, and has digestive problems. He's 48. Does anyone know if all of the above are symptoms of CVID, or whether they could be symtomatic of another disease? I would greatly appreciate any help. Many thanks.
