I am in the medical field (not a doctor) and those symptoms sound like an allergy. In our culture we feel milik is good for us as it contains many good things for us. On the other hand it contains traces of antibiotics, hormones, blood, pus, pestisides, Casein, found in milk is a substance that can cause allergies. The common allergy symptoms are excessive production of mucus and headaches. Soy milk is an alternative. I hope this helps.
