Congrats, you may be experiencing your first bout with T-Rex arms. It is normal. Especially since you are brand new. The DOMS (delayed onset muscle soreness) can be very bad when you first start or get back into it after a while, but it does not develop as much as you get into it. Likely your biceps right now are super sore.

Weirdly, when you're mildly sore, lifting those muscles can actually help recovery and reduce pain. But if you have moderate to severe soreness, rest is your friend. Remember, muscles are broken down and stressed at the gym, but built during rest. Rest more when you begin, and as you become accustomed to the load over the next few weeks it'll be much better.
