I have a lump that has appeared on the inside of my knee overnight. It is the same colour as my natural skin and the size of half a golfball. it isn t sore but uncomfortable when I use my knee. It is hard and feel like bone but I know obviously that this is not what it is. Are you able to help?
Hi! Thanks for your query on Chat Doctor! After going through your problem of the lump inside your knee, I must consider following possibilities as per ultrasound/needle biopsy reports in my clinic:1. A bursa or degenerative benign cystic lesion: 50% possibility2. A ganglion or benign amyloid cyst 20% possibility3. Acute synovial collection or effusion due to arthritis or irritation: 20% possibility4. Recent hematoma or some benign cyst 9% possibility5. Malignancy 1% possibilityTherefore, it should be investigated properly, and you must not neglect but get it to some doctor for imaging and needle biopsy if needed to relieve your concerns!regards,
