[|Human|] Hi, My 3 year old son has been complaining about a sore knee for about a week and a half now (back of his right knee) this morning he couldn t walk and was crying with the pain so started crawling around rather than walking. This lasted a few hours and seemed to wear off although he still walked with a slight limp for the rest of the day. He has also been complaining of a sore tummy, Im not sure if this is related. I took him to the doctors today but she seemed quite uninterested and told me to give him neurofen 3 times a day. Any ideas?
[|AI|]  Hi... by what you say I feel that it could be a common viral infection which is causing both tummy upset and reactive arthritis in the knee joint. This is a very common scenario which occurs with diarrhea and reactive arthritis. Usually this should settle down in a couple of days or maximum 1 week. If it doesn't settle down I suggest you approach his pediatrician with this tip once more. Regards -
