I have a small knot behind my left knee accompanied by a small bruise. It is soar to the touch and tender when I bend my knee...but it does reside in the bend of the knee. Otherwise, no soreness, redness or fever in the leg/knee. I may have I injured it but dont recall how or when. What could it be if not an injury?
Hello, Thank you for using Chat Doctor. I read your question and understood your concern. This could be a Baker Cyst filled with fluid from your knee due to some overuse activity you may have or arthritis. You need to do an ultrasound examination of the soft tissues of the knee and take non-steroidal anti-inflammatory medication, rest, ice therapy and keep the leg elevated for few days. If your complaints still persist after 2 weeks than you should do an MRI of the knee wish you quick recovery.
