i have had above knee amputation in 2010 after a bka in 2008 due to osteomylites/ this past may i had Dr due surgery to remove a nerve when i woke up he told me he removed a grapefruit sized mass from anteriuor side at end of stump. As this was going on none of the mri s with and without contrast showed the 1st mass. In the last 5 months i have a mass on the antirior femoral end that has grown to size of tennis ball and smaller one 2 inches above it/ had mri 2 weeks ago with and without contrast/ Dr advvised radiologist belived it was scar tissue but i had to show my Dr how to look at the mri in rainbow wich showed alot of hot spots/ The dull aching pain is always there barely in control along the front lenght of femor stump/ also devoled severe nerve pain in last 12 weeks and they put me on Nuronton wich helps with the shooting never pain/ should i be concerned about the pain Dr does not want to operate due to risk of infection but is recontacting Radiologist/ I am worried with not seeing the first mass removed in may on mri and now pain is worse and and devoleped never pain/ what would you advise me/ i want to dig out the bone and mass with a knife it hurts so bad/ should i encourage my Doctor to surgicly go in and see what is there or what? At this point and time my femoral stump is right agaist the skin there is no cushion and i am afraid if i fall the bone will just go through the bottom of my leg. Thanks Joe Carter Delaware usa
