Why are the skin tags on my neck and armpits increasing?

I'm worried because the skin tags around my neck and armpits have been growing larger and larger lately. They seem to get better for a while after I scrub them hard in the sauna, but I'm not sure if they'll come back and spread over time.

I'm curious about why these skin tags keep growing and increasing in number, and whether the harsh scrubbing in the sauna can affect them. I'm also curious about whether they can spread to other areas, and how to manage and treat them.

I'm confused because it seems like it will reappear and spread over time. I'm wondering if I should see a dermatologist in this case, or if treatment is a cure. I'd also like to know if skin tags can spread to other areas, and if there are any management methods to prevent recurrence. If so, please let me know if health insurance covers it.
