<s>[INST] My husband has a swollen knee and has had a pain in the mussel in the back of his leg for a week now. HIs dr. gave him a mussel relaxer.. I have given him Alleve as well. he is not getting better DO you think there is water in his knee? Dr. said if he doesn t get better he will need to see a specialist.. DO I take him to ER or wait until Monday to call Dr again? [/INST] Hello, I am understanding your concern, this either can be due to some injury to ligament, cysts inflammation, infection in knee or arthritis. If it is due to accident or injury rest and avoid activities that cause pain. Avoid putting weight on your knee. Apply ice. First, apply it every hour for up to 15 minutes. After the first day, apply it at least 4 times per day. Cover your knee with a towel before applying ice. DO NOT fall asleep while using ice. You can leave it on too long and get frostbite. Keep your knee raised as much as possible to bring down any swelling. If there are some other reasons u must consult to doctor. They may recommend you x-ray or MRI. After than treatment will proceed for the specific diagnosis. Thanks I hope you will get help with this. </s>
