I am having surgery to remove the Plantar Fibroma lump in my foot in 3 weeks (I understand the risk & heard all the stories), however, I also have a torn Rotor Cuff, and I'm not sure if the crutch will cause more pain by pushing upward under my arm. Does anyone have an alternitive way I might possibly get around this? (Wheelchair is out of the question). I appreciate any insight regarding this question...Thank you in advance...Metzie.
