Hello! My dog was just neutered, and..

Hi- My name is Christina and my maltipoo, Max was just neutered today- He is a year old and is about 8 lbs. I picked him up about 3 hours ago, and he will not relax ever since. He had an undescended testicle so they had to make 2 incisions. Whenever I try to pick him up to carry him to my bed or somewhere more comfortable, he yelps and tries to run away from me. He freaks out so much that I'm afraid to touch him. Is this pretty common? I'm not sure what I need to do. He's just standing there, looking sleepy and tired... and it's breaking my heart
