my legs get irritated after shaving???

Ju
For years now no matter what I do my legs get soo irritated after shaving. Razor burn sometimes, but sometimes they are just uncontrollably itchy and I itch until they bleed!! Sometimes they seem to have hives or ingrown hairs idk if that is just razor burn. I've tried different razors, different creams and conditioners, moisturizers! Every now and then they'll be ok for a while and then just get out of control. Everything online suggests changing razors and moisturizers. Wondering if anyone else has this problem and what helps them??!
