a few days ago i slipped and fell, the next morning i had pain between the bottom of my tailbone and rectum, the next day there was swelling in that area, the area broke open the following day and relieved the pain, there is still a small amount of discharge from where it broke open, now i,m worrying it could become infected,i,ve been having night sweats but no temperature, do you think i need antibiotics, and do you do online prescriptions?
