Why do alot of Doctors rule out parasites as part of hernia?? OB?GYN say different, they say that female yeast infections ,mens jock itch athlete's foot are all under candids. Told that alot of animals rather pet's, farm animals wildlife all care parasites, which anyone can pick up from working in dirt from garden ,pet's just being bare foot walking around outside. Signs possible are night time itch of backside. stomach area bloating, craveing of sweets. bread. starch food which breaks down into sugar.
