2. Red, Swollen Tonsils
In some cases of strep throat, the infection may spread to the tonsils causing redness and swelling. White or yellowish spots may also appear on the tonsils. There may be streaks of pus covering the tonsils as well, easily visible on investigating the throat. In rare cases, red spots may also appear on the tissue surrounding the tonsils, i.e., the hard or soft palette (the region at the far end of the mouth). Many a time, these symptoms may lead to a condition being confused with tonsillitis. When such doubts arise and the cause of the inflamed disease is unclear, doctors usually order a Strep test to check if streptococcus bacteria is responsible for the infection. If found positive, the indication is clear and a course of antibiotics may be started promptly.
