My throat was hurting?

Last night my throat was hurting and I didn't feel well. I get strep throat all the time, so it seemed like i had it again and it was not strange for my throat to be hurting. Oh and btw I went on this school field trip (a 2 day over night thing) and when i came home i had a very runny nose, a flem cough, and a sore throat. I had an ingrown/infected toenail (lol a lot of problems yeah yeah yeah, i know) and i had to take pills for it. The day before yesterday they had been making my sore throat feel better as well as my toe. But i stopped taking them the day before yesterday, so last night my throat started hurting. I am only 13 and i go to bed at liikee...11 each night. I don't know if this is "not that bad" or whatever but I realllllyy need my sleep, but i hate going to bed. Last night my throat was hurting bad, not like the strep throat kind tho where it is all sharp pains when u swallow, it is like my throat was too hot and it was being like pushed out from the inside and, stretched sort of you know? I took Motrin last night and it made it feel better. Well this morning I woke up and i still wasn't feeling well. I told my parents and they said it was okay for me to stay home. I went back to bed and slept for 4 more hours...until now. I woke up a few minutes ago and my throat was feeling fine. It didn't hurt to swallow, although i still do have aches and pains. So...what was wrong with me? Please help....was it wrong for me to stay home? Because I love my parents and if i'm up and about instead of in bed i don't want them thinking i lied to stay home or something, because I would never lie to my parents for anything.
