That is actually true to a certain extent. Most of the time you need to have some sort of sensitivity/allergy to dairy. But dairy products can increase the thickness of your phlegm, therefore can clog up your sinuses, and eventually cause the sinus pressure.
Answer: Your Question: Fever is the body's way of fighting infection. It may be in combination with other symptoms of illness. Milk curdling is not specific to having a fever. When you're ill and not feeling well, almost any food will curdle if the stomach can't properly digest it. Because of it's specific protein content, milk and diary products tend to coagulate or curdle when mixed with stomach acids that normally digest food we eat. The digestive process slows down or speeds up (depending on what the problem is). Another problem that may cause the curdle is something called REFLUX. This is commonly known as heartburn. It occurs when food and digestive acids come back up the food pipe (esophagus) when partially digested. Milk and other foods appear to look curdled.
