Hi, I and my husband last couple weeks having the same problem. After eating we start having some unpleasant feeling in our forehead,some tension, sometimes itching, then all spreads over the whole head, get uncomfortable feeling in stomach. It lasts for an half hour or more. Feel bad overall, very tired. Since we have the same problem we thought that we might got some parasites in our system? May be you have some idea what we have? Thanks
