When doing push-ups, there are tendons jumping on the arms, as if the harder the blood vessels are, the more painful they are. Will the blood vessels rupture next?
If you are young, you should have no problem. What you are talking about is the normal physiological state of blood vessels, because during strenuous exercise, people's oxygen consumption will increase, and oxygen is transported by blood, so blood vessels have certain elasticity, so they will feel bloated than normal. If you want to feel comfortable, I suggest you warm up before doing it, let your body adapt, and then do relaxation exercises after you finish it, which is better.
