i am at a complete loss...my 6 month old has been grumpy all morning and only wants to be held. he's usually never like this and i don't know what it is...

he's been drooling, putting stuff in his mouth, i see two raised bumps on his gums (but nothing is cutting through)...his temperature (taken by forehead) is 98.6 degrees..

if he is teething, can i give him some kind of medicine?
