58y/o female- sore, warm to the touch, quarter sized lumps below her Achilles' tendon. Will call doc Monday if not gone, but could this be gout?

Is it possible? Yes. Does it sound like it? Not really. First off that's not really a joint area and gout usually affects joints. Without seeing the lumps it is hard to take a guess....I am it sure why hey would "disappear" by Monday.....if there is anyway you can show us a picture that would be helpful in us helping you.
