Since Monday I notice pain near my rectum today after investigating further I found that I have a large, hard, lump mass underneath the skin on my left butt cheek, no it the rectum/anus itself but more so underneath the skin of the lower left butt cheek. My Dr. does not have any appointments open till the 20th. Should I go to the ER. Is it cancer?
Welcome to Chat Doctor. 1.No, the history you have given does not suggest any cancer, it only suggests a superficial/ subcutaneous lump with pain.2. That could be hair follicle infection, lipomas, or superficial abscess.3. Would recommend you to see the doctor / GP, he will examine the case and do needful investigations done.4. If there is any pus discharge / collection noted - a course of antibiotic would help.5. If in case its bigger a small incision and Chat Doctor.  Good luck. Hope I have answered your query.Anything to ask do not hesitate. Thank you.
