Hi
Of course it could be a number of things but..
your story resonates with our last few weeks of teething experiences.... whilst our LO is 10 months a couple of bouts of teething have been exactly like that, he would wake crying and tired but couldn't get back to sleep on his own .. and had to fall asleep on me when otherwise he is an independent sleeper. He didn't want to be alone in cot and would need to be held until back asleep. And yes paracetemol didn't seem to work at those times either, I think he just felt miserable as well.. and was needing cuddles from Mumma. It's very stressful and hard to see LO like that isn't it?
I hope your LO is feeling better .. that sounds very hard for you.
did you try some teething gel? Although if the teething is bad that doesn;t seem to help either.. the only way to know if it was teething is to wait for the first swelling of the gum to appear. FOr our LO that takes two weeks though!!!
