Can I dissolve strong thread types like PCL, Aptos?

My surgeon added a strong thread & told me it goes to the muscle (platysma muscle I guess) & that it lasts longer than other threads. After the procedure I asked him about the product so I was able to see it & touch it. It's been 3 months & I do feel a discomfort, as if something's stuck on my neck. I'm freaked out but calm. I will soon go to him but I want to be prepared from you so I won't get gaslit or anything. Can such thick thread get dissolved by treatment just like short-lasting one?
