If you have relatively identical bumps at the upper forehead (you mentioned two bumps), then I suspect this may reflect the bony curvature of your skull bone. If this is the case, then the most simple and satisfying treatment may be to use fillers to smooth out the contour of your forehead. 

If you have asymmetric bumps, then these may reflect bony thickening called osteomas. These benign growths can be addressed by shaving down the extra bone. 

I would recommend a thorough evaluation with a facial plastic surgeon.
