Hi buttquestion,
In reply to your question about a chronic or an acute anal fissure: if a fissure has not healed after 8 to 12 weeks, it is then considered to be chronic. This is why it is important to see a CRS (Colon and Rectal Surgeon) for a diagnosis. They are the ones that see this every day, and deal with them if necessary. Not all of them operate. Mine did not. Most of us have found that a GP is absolutely useless in diagnosing this.
You do not need to have a skin tag operated on. I have 'kept' mine, and do not intend to touch them. It is also known as a sentinel pile. You can research both on here, skin tag and sentinel pile. Skin tags are one of the joys that sometimes come with an anal fissure.
A good CRS in your area. Here is a link:
