I use Tea Tree exfoliating scrubs.  You can get different aromas from drugstore.com or Ulta.  On the other hand, it might be a good idea to see a dermatologist about your problem.  Good luck.

I totally have your same problem (though my bumps look more red than brown). According to our Hair Removal 101 article applying pre-shave oil or olive oil three minutes prior to shaving can help. You get get some more hair removal tips here. Good luck!

Use a sharp razor. I throw mine away after about four uses, because they get too dull and cause razor burn and ingrown hairs. I also have to use a generous amount of shaving cream. Yes, it did seem wasteful at first, but that's what it took to keep my legs looking nice. Exfoliating can also help. I love Giovanni's Hot Chocolate Sugar Scrub. It made my skin SO SMOOTH!
