I have these razor bumps on my pubic area dont know if I should be concerned about it?

Less often and close. Razor bumps are common. They are not dangerous but are a nuisance. I have heard many recommendations; here are mine culled from my 32 years as a doctor: Avoid close shaves- use electric foil razor or new twin-blade with foam. Avoid frequent shaves- wait as long as you can. Only move the razor ONCE over each skin area. Here are other ideas: https://www.symptomfind.com/health/get-rid-of-razor-bumps/
