Welcome to OCF! So sorry you are going thru a scare right now. Waiting is horrible and since you havent been biopsied yet there probably will be more waiting in your future.
Here are some statistics about recurrences. First, they are not as common as many patients believe. Alot of members who post frequently may have had recurrences thats due to the one timers going back to their regular lives. The info is 10 years old. I am unsure of how often this gets updated or if any more recent studies have been conducted. Read the post by OCF's founder Brian Hill.
Recurrence Stats (Old OCF Forum) Try to keep yourself busy so the time passes without too much stressful thinking "what if". I know its not easy to avoid thinking that way. If you find yourself going there, try to check the clock and say to yourself "ok...I will ponder this for only 5 minutes" then change the channel.
Best wishes!
