The bone just feels really achy like it’s been stressed.
That’s no shock - your bones ARE being stressed. Weight training delivers mechanical stress to bones, which is why it is a good tool for preventing osteoporosis.
The reason your bones hurt is because they hold a slight degree of elasticity to them (aiding in injury prevention), so my guess is that the pain you are feeling is the result of a slight (imperceptible to the naked eye) bending of the bone as a result of the higher weights you are curling due to your stronger biceps.
The fact that you haven’t curled in a while is evidence of this - heavy barbell work places a unique stress on the bones in your forearms compared to most other lifts, so it makes sense that your forearms haven’t developed accordingly during your hiatus from curls.
It happens all the time (happened to me a couple weeks ago, actually). I don’t know how long it has been going on for you, but quality diet/rest should take care of the problem within a week or so. If not, then lower the weight, increase the reps, and build back up slowly.

I never have done many curls in the first place. This is my first-ever bulk and as a newbie to gaining muscle, I took advantage of the full body workouts consisting of mainly compound movements and very rarely a little bit of isolation.
There’s those big arms, small torso guys out there, and then there’s me, the opposite. I have a big torso, but I don’t have the arms to match. In realization and admittance to this, I decided to add a pure arms day at about month 5 of my bulk. I believe this new stress began hurting my arms over time.
The pain may be a buildup over several weeks and the pain just happened to come when I began doing barbell work by coincidence or it could be from when I began doing barbell work. Dumbbells beforehand never gave my any real bone aching like the barbells did. Now when I even go to do dumbbell work, my forearms will begin hurting.
Do I need to strengthen my forearms? I suppose continual heavy lifting with my arms could possibly remedy this dilemma. By the way, my biceps aren’t that strong, I don’t think. I can curl 40 lbs per hand 6 - 8 times, which puts me at a max curl of around 100 with a barbell maybe.
