my mother is 81 years old and has severe pain in the crease of her leg behind her knee . The other day she could not get up by herself - had to be lifted. She also has some bumps - looks like clumps of blisters below and in the crease. Also has hardness the size of an egg above the crease of her left and right legs in back of legs. Her legs are also very swollen and hard. She also has high blood pressure and atrofibrilation. The bottom line is that today she can get up and walk only with a walker - the pain in her left leg comes and goes. She said when it first started it was the worst pain she ever had. Now, it goes from level 2 pain to level 8 pain.
