[|Human|] I am 60, female and have had relatively good health. I just went to my OBGYN Mon. Heart Rate 57, BP 117 over 68. I went for a 6 mile hike in the Mt. Tues. Felt fine, no problems what so ever. I used to exercise 6 days a week stedily17 years. Last 7 hit and miss. Last night when I went to bed my left knee was puffy in 2 places and felt stiff. I ve never experienced that before. I had root beer floats twice in the last week. I never usualy have pop. I wonder if that could have some effect on what I experienced. Its still puffy and stiff today. Dosen t hurt.
[|AI|]  Dear Sir/Madam have gone through your query and read your symptoms. In my opinion, the symptoms are a sign of exertion of the marginalized knee, the symptoms are coming under control and will get ok with time, but you need to be aware that if you exert in future this may recur. The key to control is regular exercises. I hope that answers your query. If you want any more clarification, contact me back.
