Tennis elbow--chopat strap

Has anyone else ever used the chopat tennis elbow strap while swimming? I (foolishly) have been painting my whole downstairs while also upping my swimming yardage and weights. Today I suddenly couldn't straighten my arm without much stiffness and minor pain. It sounds identical to what my husband had from lifting months ago. He was diagnosed as having tennis elbow. I have caught it early (I think/hope) as it hasn't hurt at all before today and it doesn't hurt when I don't try to straighten or twist. I'm not sure if I should swim with it or not but thought I'd ask about anyone else's experiences. I'm kind of hoping that stopping the painting will allow me to swim after a few days. Any thoughts???:help:
