<s>[INST] Hello, my right knee is very painful, swollen and cracking after a loud crack the other day while walking. The pain is getting much worse. I don t have insurance until Nov 1st and was wondering if I should go to the emergency room or give it a few more days, It s getting to the point where it s near impossible to walk. [/INST] Hello, Your symptoms could be related to a ligament rupture or Monique damage (part of the knee joint). For this reason, immobilization may be needed. I recommend avoiding walking and putting some ice on the knee, have some rest and taking ibuprofen for the pain. If your situation does not improve, consulting with an orthopedist and performing a knee MRI may be needed. Hope I have answered your question. Let me know if I can assist you further.  </s>
