instruction: hello doctor a doctor gives an injection to my mother after 45 days that starts to pain with swelling and red area of about inches I checked again he asked to take oxidil iv injection after six oxidil injections the pus comes out and the red area decreases now pus does not come and we are using a bandage on it oxidil was stopped now and after about one week pus comes again today and the red area is about 5 square inches the area below that red is hard what do you suggest should I use some more oxidil or augmenting she is 65 years old and we are trying to avoid surgery kindly guide me
output: hello I understand the problem your mother is facing according to the history you have provided I believe she has developed injection site abscess though it is not uncommon in elderly people it can happen your doctor has started her on a single antibiotic injection oxidil ceftriaxone but it is my opinion that it is better for her to undergo incision and drainage procedure it is a small procedure once wound is opened she will have immediate relief following by antibiotics if she has no other conditions such as diabetes her wound should heal within a week or two if you continue to treat her only with antibiotics oxidil I believe it will not subside completely and it will reoccur she should have also been given injection metronidazole iv thrice a day if pus is present if you send a picture of the wound site I can comment further in my opinion surgery is still the best option I hope this helps
