medic alert bracelets / necklaces for lymphedema

Hello folks!

I have not been online for a long while, many thanks to my aging computer! Just got a new PC at last, gratefully!

Now, I am in the process of ordering a medic alert for lymphedema prevention. I just cannot decide between a bracelet or necklace.

I had lymph node dissection in my left armpit (18 nodes out). I have yet to experience lymphedema. I think that a bracelet would fit me better, but then it would catch attention from people whom I interacted with.

So, I would like to hear your input / experiences with medic alerts.

Thanks & hugs! :-)
