Are you getting your face and neck clean before your shave? Get a good face scrub, with acetylsalicylic or salicylic acid, and scrub before you shave. I also took a bottle of witch hazel (mine has alcohol in it) and dropped in 10-12 uncoated aspirin (acetylsalicylic acid) and use after shaving and again at night after a good face scrub. I used to get bumps like yours no matter what I did, after just a week or so of scrubbing and treating with the aspirin/witch hazel its getting much better. As always, YMMV. Good luck!
