That is a totally unacceptable post from Safinamo who I believe to be a troll. I have reported the post to the moderators.
Susie, plaque on the teeth is furry but eventually hardens and becomes difficult to move. Plaque in the arteries gets furry and can break off to cause problems like stroke or it can become hardening of the arteries. Presumably plaque in the area you describe is similar - but rather than ask non-experts on here, you should give the GP a call and ask them to explain it.
