I have been dealing with an infection on my knee for about 2 weeks now. I am on Keflex 500 mgs 4 times a day now since Sunday. Doctor saw me in the hospital yesterday. Blood work cam back ok so they sent me home. When I got home it opened up. What a mess. I am in contact with the surgeon each day, sending pictures. I just saw him on Thursday for a 4 mo. check and he did not put me on antibiotics at that time, when it was not as bad. It is painful, but feels better now that it is open. I have to keep it covered in gauze; it it draining some during the day and night. I am 2 attaching photos; one yesterday before it opened and the second is after. Anyone ever see anything like this and know what could have caused it? My incision was completely healed and looked great. This is actually above the incision. I see the surgeon on Friday, but I am still quite worried especially now that i is opened. If you loook carefully at the second picture, you can see there is a hole. Thank you for any help.
