Razor rash

Does anyone have tips on how to relief razor rash/bumps? I only shaved downwards thinking it wouldn’t give me any bumps but it did! And I was planning on shaving again tomorrow as it’s my birthday and my S/O is taking me on a road trip☹️I’ve just put 100% aloe Vera gel there which soothes the swollen feeling but it’s way to sensitive and irritated to shave over 😩😩
