Lymphodema

I have often thought about this.

I like the comment from the doctor though that if you are not in a position to let someone know not to use the arm in question then you are probably needing real help....it won't matter what they do to save your life.

That makes so much sense.

I even contemplated getting a tattoo but it sort of defeats the purpose to have a thousand needles stomped into your arm to give an alert that you shouldn't have any needles or cuffs used on that arm............

I have found a medic alert bracelet that comes in all sorts of metals and value..... www.identifyyourself.com

Perhaps you could look at that and it would give you some options that give you peace of mind.
