I went through 8 months of PT for this exact issue. My pain first came when I was shaking hands with a bunch of people at a business dinner. I remember specifically shaking and after i let go my arm burned so bad. Musketeer hit it directly on the head.....layoff for about a week(at least). The heat thing in my opinion is a very bad idea. The more you heat the area up, the muscles & tendons expand and create even more pressure and throbbing. What worked for me is ice at night. 20 minutes on/1 hr off..(over and over until bedtime) and Advil 400mg every 4hrs. Additionally, at night before bed i would run my thumb down the area length wise to straighten everything out. It aggravated the shit out of it, but thats why i did it at night so i could sleep through the pain. The only why I could stop the throbbing after i healed was to wear my staps for everything. I curl, do tricep work, back work, whatever I can with straps. It might look odd, but im the odd guy with no arm pain.
