<s>[INST] I m 76 years old and about 5 days ago I started feeling a really sharp pain on the right upper part of my knee. I ve been limping because walking is extremely painful and if I sit for too long I have to stand and wait a while before I can walk....what might this pain be or mean and what should I do? [/INST] Hello, As you are 76 and having pain in the upper part of the knee, have you ever taken an x-ray. Because there should be some degenerative changes of the knee joint and the ligament injuries.  Having an MRI or X-ray will be of God choice to understand the pathology.  As this pain makes you slow down and locks you up while taking instant movement I will advise you to use the knee brace and do hot water fermentation.  Because the muscle spasms need to be corrected, and also the weaker muscles needs support, so the inflammation over the knee joint internal structures do not go high.  Also doing some simple exercises like - static Qua Chat Doctor.  Additional exercises like straight leg raise on supine lying and side lying will be of benefits. In my clinical practice of over 12 years, most geriatric cases reported with similar pain are advised for exercise in low intensity. They respond well. Hope I have answered your query. Let me know if I can assist you further. Take care Jay In </s>
