Customer Question

I noticed a lump on my upper arm this morning (outside of my arm, not near armpit), it is sore to the touch but there is no bruising or discoloration. Do I need to see a doctor about this on Monday if it is still there, or since it is sore is it likely to have been caused by a bump or injury? I can't remember doing anything to it but it's possible that I banged into a door or something and am not recalling it. Or is this more likely to be something serious? I haven't noticed or found anything else on my body and don't have any other symptoms.
