Suggest Treatment For A Sharp Pain In The Forearm

I am a 24 year old whte male with no recent medical issues. For the past serveral days i have noticed a sharp pain in my left forearm when extending my arm fully in a push-up manor. More recently i have noticed a slight red line racing up and down my forearm in the exact place of the pain, and today notice the pain reaches from my triquetrum bone on top of my wrist to my arm pit. It does not restrict normal lifting but restricts my ability to push heavy items. Normally I would just take some advil but it is moving up my arm towrad my heart and i dont want to ignore it. Any suggestions?
