I was in the ER on Saturday afternoon with pain near my anus. I had a an abscess once when I was 27 and am now 48. The feeling was similar. They ER doctor said they was no pronounced lump, but the CT scan showed that an infection was forming and that there was irritation. They sent me home with antibiotics and told me to take warm baths. I started the antibiotic Saturday evening and have now taken three doses. Sleeping last night was horrible and I was in a lot of pain. When I woke up and started my day, the pain wasn't as bad, particularly if I was standing. But, The pain has worsened this evening and I'm having trouble sleeping again because I just can't seem to get comfortable. They told me on Saturday afternoon to make an appointment on Monday morning with the surgeon. Should I wait or go back to the ER?
