These are just inflamed hair follicles from close shaving.
In future first soak the area with warm water first and then apply shaving gel for 5 minutes at least.
Use single blade or guarded system to avoid razor bumps.
Now coming to the treatment part for immediate relief, you should get benzoyl peroxide gel or soap and apply daily.
Then apply hydrocortisone cream available over the counter twice daily.
It may take a week to see significant improvement.
That is as fast as you can get with over the counter remedies.
It was my pleasure to help you today.
