According to the information you reported (shaking, getting chills, headache, pain in legs and fingers, fever of 101.10 degrees, sore throat and sneezing, your brother diagnosed with bad cold and throat infection), it is possible that you might be experiencing a cold and throat infection.


In most cases, a cold is caused by viral agents, one of them being flu. While a common cold is presented usually with inflammation and symptoms from the upper respiratory tract (running nose, sneezing, coughing, headache, and fever), in the flu, pain all over the body is present, too.


Whether this is caused by H1N1 flu cannot be determined because it is only one type of flu.


You might want to visit your family doctor for a physical examination. If a suspicion for H1N1 flu infection rises, then you might be referred to a specialist for infective diseases for additional laboratory tests, which would reveal whether you are infected with H1N1 flu or another type.
