I have developed a lump just smaller than a golf ball on the lower left are of my knee below the knee cap. I can ony feel the lump when I straighten my leg. It is painless and feels hard. It flared up after I had a holiday 5 weeks ago where I did alot of walking. I have plantar fasciitis could this be linked?
Welcome to Chat Doctor. 1. The features with history suggest that most possible cause would be ganglion (a fluid collation cystic structure). 2. Which arises from the joint space entities - tendon, bursa, nerve sheet, cartilage, ligament.3. The next step in this is they are general slow growing pain less lumps - one has to monitor the growth.4. If any discomfort or pressure effect seen at the joint area - a small incision and Chat Doctor. 5. An ultrasound scan will be good to evaluate the nature of the lesion and its source and extension, But best tool will be MRI for knee joint and adjacent structures - good luck. Hope I have answered your query.Anything to ask do not hesitate. Thank you.
