what pain relief can I take?

My 3 year old little boy has got hand foot and mouth disease. He's spent the last 3 days laying on the sofa being carried to the toilet and bed. He's got no energy, his face and genitals are so sore and scabby (the skin on his bum is literally peeling off I could cry for him) docs said he can have paracetamol and it'll clear up soon. only thing he's had in 2 days is drinking milkshake through a straw!just wish I could "fix it" I've woken up today with swollen glands and what looks/feels like tonsilitis. currently 11 weeks pregnant. What pain relief can I take?
