Wow, so glad you caught that and it turned out well.
When husband had a swollen lymph node in his groin, the doctor wanted to immediately cut it out without looking into why it was swollen. A few days later, the same doctor ignored husband's leg which was bright red, swollen, and hot to the touch. This same leg was reconstructed after a 3 story fall in the early 90's. Thanks to my sister in law, who's a charge nurse at the univeristy, she got us a new doctor and he caught the staph infection in the hardware in that leg. Very scarey stuff.
