Anyone else’s stump have a silicone allergy?

Hello, I recently had my right index and middle finger amputated, reattached VERY briefly, then amputated again. My physical therapist switched me over to a silicone stump shaping cap today and warned me that, though extremely unlikely, there’s a chance that I could have a bad reaction to the silicone and need to remove the cap. Come 11pm I started feeling an intense pain that was worse than the usual burning. I tried to wait it out for a few hours until it became unbearable and I had to take the new cap off. The pain went away immediately and I noticed that my stump was red with a sizable blister so I’m assuming this was a reaction to the silicone, though I thought that the chance of a negative reaction was quite rare, especially for medical grade silicone. Am I just unlucky and happen to have a genuine allergy? Anyone else experienced a bad reaction to it?
