Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint pain and swelling in knee can be due to causes like Traumatic injury to knee, Arthritis, Bursitis, Gout, Pseudogout, Rheumatoid Arthritis, Bakers cyst etc. I would suggest you to consult an Orthopedic and get evaluated and a thorough clinical evaluation and investigations like x-ray, MRI Scan, blood tests etc. can help in diagnosis and treatment can be planned accordingly. You can be advised to take anti-inflammatory painkillers like Ibuprofen for pain relief and topical application of analgesic ointment like Veteran. You can be advised to follow the most common technique that is R.I.C.E that is REST which means refrain from workout, sports, vigorous walking, long hours standing etc.ICE: Do cool compresses over the joint for fifteen to twenty minutes as it will help in reducing swelling.COMPRESSION: Cover the knee using a knee cap or crape bandage as it provides support as well as reduce swelling.ELEVATION:Put pillows under your legs while lying down and raise it from the level of body. By these techniques the swelling will reduce in 3 to 4 days and in case if there is no improvement treatments like Arthrocentesis or surgery can be advised depending upon the cause. Hope this information helps. Thanks and regards. Chat Doctor.
