Tingling burn in forearm up to wrist when extending arm out flat?

Thursday I did an activity I don't normally do, I powerwashed the bottom of 8 pontoon boats with a commercial powerwasher, Just the trigger in my right hand for the most part. Well when friday came I began to notice this pain. I was reaching for something, moved my wrist, and it felt like a tingle went up my arm and then it was like a burn, and i mean a BURN, hard to cope with. Anytime I go to reach for something with my right arm it huts like HELL, today is monday and no it isn't better. Any thoughts on what the heck i did? If I put pressure on the inside of my arm right at my elbow on that tendon there, i guess its a tendon, I can feel the tingle/burn right at my wrist
