What symptoms does propranolol help with

I’m interested in propranolol since I read that it helps with physical symptoms but which ones exactly? For me, my heart does race a lot, a lot of shaking and a weird warm/burning sensation in my upper body. I also think I have tension headaches and just weird sensations in my head

I notice they get worse when I feel anxious so I’m hoping its because of adrenaline since I read that propranolol reduces that
