I am a 21 year old female. I was fine last night, went to bed early. Well i started waking up like every two hours with night sweats and felt my throat was swollen and sort of hurt to swallow. I had a headache and was just really restless and uncomfortable, even though i sleep the same way every night. Today my throat is still irritated and my headache is minor but my lower back is also starting to hurt more than normal. I am also very tired even though I should have had plenty of sleep. What is wrong??? :-(
