What Does Pain In Forearm After Weightlifting Indicate?

Hi I have been weightlifting for about 6 months and recently I feel a weird pain when I twist my forearm. It is around the unla bone, but I don't think it is the bone since pain occurs only in a pressing movement and not a motion of holding something. I think it might be a pinched nerve or a tendon. Also to add on the pain changes spots, so I don't think it is a microfractures, but if you can clarify this I would appreciate it.
