Hello, I am having this condition for quite a while now, my right knee skin has swollen and is red and hot. I think this might be a consequence of the incidence where i fell off from my bike and bruised that knee which was blue for quite a few days, and it never fully recovered. But the condition it is in now is totally different, it's become something serious and it itches a lot throughout the day. Please suggest something beneficial and soon. Thanks.
