Acute tonsillitis causes symptoms such as a sore throat, difficulty swallowing, fever and tiredness. Tonsillitis that keeps coming back within short spaces of time can be very distressing and in rare cases may lead to complications.
Obstructive sleep apnea
If you get enough sleep but still feel run down during the day, you may have obstructive sleep apnea (OSA). Many people who have sleep apnea snore and stop breathing for short periods of time at night without noticing it. This can both cause problems in everyday life and increase the risk of other medical conditions.
