Hi, I am 29. I have injured my knee about 4 weeks ago, I slipped on the river rocks and fell down on the inside of my knee with my leg bend. The knee was swollen for a couple of day and very painful. I was able to walk the next day, but with great difficulty. Now, after 4 weeks, it is still painful, especially after I get up from bed in the morning, or get up after sitting down for a longer period of time. And I am not able to straighten it. I did have an xray done, and it s fine. My GP said that it is just some soft tissue injury and it may take about 6 weeks to heal, is that true? Should I wait that long or should I see a specialist? I am just so worried that there is something seriously injured, as I cannot straighten it.
