Three days ago when using the restroom, I noticed a mass about the size of a pea had formed about 1.5 inches away from my anus. Felt like it was bruised but left it alone. The following day, it grew to the size of a Japanese peanut but discomfort followed. Swelling spread forward and reached my anus. Today, it swelled up a little more but now it brings pain when using the restroom, when coughing and seating and an additional pea sized mass formed between the original point and my anus.
