My arm is kind of aching from exercise. And I wanna know if they'll be okay to use, because I'm on medication right now.
I was reading the back of the box and it just says to ask a doctor before use if you have RA, bad circulation, diabetus, or heart disease. And the only ones I have are RA and a bit of bad circulation in my legs.
I figured it'll save more time to ask an internet LEGO forum instead of a doctor.

The medication I take is an injection called Enbrel. (link)
