If you weren't riding your drop bar bike with your hands and wrists in a neutral position, then don't blame the drop bars. That's all on you!
If I wasn't on a drop bar which offers 4 different hand positions, then I'd be using a bar that looks like the old roadster style bikes of the 50's and early 60's. The ones that the bar ends point almost straight back. Otherwise mustache bars, trekking bars or anything that gives you multiple hand positions. Not a flat bar with one hand positon that will let your wrist sag and give you the very bent wrist/hand position I'm supposing you may have had in the drops.
