I am curious to the average size of a pseudocyst? When I had my ultrasound last week it was already almost 4 inches long and 2 inches wide. I have had no pain from it, but starting yesterday have a very uncomfortable feeling in my stomach where the doctor said the cyst is. I’m hoping this means the sac is starting to form so they can drain it, or it is just getting a lot bigger and pushing against things. Do they vary in size a lot?
