Has anyone else had this experience after not using tampons for a while?

So a while back I bought a Blossom cup ( similar to the Diva cup), and I loved it but I worked at a place that didn't have a single person restroom, so cleaning properly and such wasn't really plausible, so I had to resort to using tampons again. I moved and had been unemployed for a while so I decided to start using it again about three months ago and I gotta say I still love it. However, I recently started a new job and figured this coming cycle I would have to go back to tampons. So my cycle started and I use my usual tampon that I've been using since I was 11, so about 10 years now, and I swear ladies I felt like I was burning from the inside out. Like someone had poured acid on the tampon or something and I immediately went and took it out and replaced it with a different tampon and got the same result. So I decided to use my Blossom cup and I have been perfectly fine, and haven't felt the burning again, and luckily my new job has a single person bathroom. Has anyone else had this happen? I'm wondering if whatever chemicals they use in the tampons caused the burning and since I hadn't used them in such a long time that my body was no longer use to it. I don't know what do you guys think?
