Anyone know of any good products to treat razor bumps from shaving? 
Try switching razors. You’re probably never going to find one that’s perfect, but some are better than others. Also, don’t go over the area that you’re shaving several times at once.
There’s “shaving powder,” a depilatory intended for use by Black men, for whom razor bumps are a common problem.
I have found that a beard works quite well on razor burn. Silply allow it to grow in the affected areas. After a few months, there will be no remaining trace of razor burn.

Having worked at a Rite Aid for 18 months a few years back, I became quite well-acquainted with the shaving-bump section of the men’s toiletries aisle. There were four or five different products located near the shaving cream - I can’t imagine they’d be anywhere else - to treat shaving bumps. I can’t remember any names right offhand, but if you haven’t looked pretty hard at the aisle, it might be useful to.
