<human>: i have several balls around my knee area that really bother me. it hurts to stretch but after i am warmed up i can complete my entire work-out. unfortunately, by the next day i am feeling the pain. i have gone to get a massage where the balls have been broken and the pain goes away. my question is it safe to have the balls broken? is there a general cause to getting these horrible balls?
<bot>: Hello, Where is the exact location of as you said ball?  How much is the size of each one. Possible causes are:1. Bakers cyst.2. Bursitis.3. Arthritis.4. Meniscal cyst.5. Boils. Until examination is done it is difficult to say what it is. Please take me a photograph and send me or consult with your orthopedic he will examine and treat you accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further.
