I have painful small lumps on the inside the bottom of my right foot with pain radiating to the top.  I cannot put weight on my foot.  Also, I am running a fever.  I live in Lao PDR, a least developed country and dont have a lot of confidence in the medical system here.  Should I get an ultrasound to see if the lumps are visible?
