Hi doctor, Before 10 days, I got a cut on my knee. Two days later, I swam in the contaminated water. Then, I realized that my knee was extremely red, inflamed, tender and spreading outward from the site of the cut (first image). I cleaned the wound with alcohol and did not seek treatment. The following morning, the redness had gone down, and there was less tenderness. Three days later, I started on antibiotics (Cephalexin) four times a day for 10 days. The doctor who prescribed the antibiotics said he was concerned it may be a septic joint. The second image was taken last night. Should I seek further medical treatment for the septic joint? I can walk, run and bend my knee. However, it is a bit stiff. I am not sure if this is just the scab. I do not want to leave this and allow the condition to progress. I also have seven more days of antibiotics to complete, so I do not want to jump to conclusions. Please advise.
Hi. I have gone through your history and the images (attachment removed to protect patient identity). Ultrasound knee. For further information consult a rheumatologist online.--->
