Tingling and burning are ongoing, and the knee hurt so bad that the consumer thought about going to the ER but did not due to fear of exposure to Covid-19. Consumer reports seeing their primary care doctor about their symptoms but that the doctor did not know what the hardness was.  There is a milder severity on the side of left leg.    Bruising on left leg phased away last week but the knot is still present.
