I have a recurring calous , it drives me mad sometimes. Theres a small shard of glass embedded deep in my foot and it keeps a constant irratation that builds a callous right there.
Initially I had gone to Kaiser, to see what they could do, Doctor sent me to the podiatrist , which I guess was their specialist. However I was shocked when she didnt even bother to look through a magnifying lens... just pulled out a metal tool which must have been a medeival cheese grater.... rubbed some topical numbing solution on the area... and told me she was going to try to remove it this way. Told me to let her know when it began to hurt too much... (which was almost immediately). but I tried to hang on as long as I could because she was really really cute.... I lasted 30 seconds maybe and then had to tap out. Needless to say I still have the shard and didnt want to go back to those people.
The podiatrist's name?? Dr Lancer. Not kidding.
