Advice pls

I have a 8 month bby boy having a fever past 2 days. Went to private clinic they say its normal for baby to get sick as its his first time falling ill. Doc check everything n say his ok. Still look strong n good. Good thing is that his temperature is down. But he keeps on crying non stop. N like nothing can stop n comfort him at all. He only stops crying when he went to sleep. He still can eat a bit n drink milk. He suck his pacifier for awhile then throw away. Not sure if its something in the mouth(no teeth btw). Doc just say give him time, he looks uncomfortable n just try to comfort him. But what else am i suppose to do as i did tried lots of thing. So i need some advice pls... 😫
