So, I thought I would update on my experience with using Opsite film as a barrier to stop the reaction of my skin to the Freestyle Libre sensor's dreaded adhesive.
Basically, it didn't work!
It did last the course from a stickiness point of view - just about - and the injuries left on my upper-outer arm's skin are not QUITE as bad as before, but still weeping and red - with a more pronounced psoriasis-like cauliflower-like roughness to the skin. The redness pretty much follows the sensor adhesive patch's dimensions (although not as perfectly well-defined as without the film). Question is: how did it (whatever "it" is!) get through the film? I know it is a breathable film - so, maybe there was some of "it" crossing the film; enough to set my skin off again, anyway.
One thing I WOULD like to know is this: to what ingredient have I been made hyper-allergic to by this sensor? Will I encounter said ingredient again in other walks of life / adhesives in a medical setting. I'd like to know. Abbott customer care would not tell me as "it's proprietary". Although, given it is a medical device, you would think it would have to be pubic knowledge. Maybe I should go to my doctor and get her to ask the question of Abbott...
Anyway, I will try a Compeed patch next - and maybe also the Cavilon spray. Although, I have my doubts about the spray...
