<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have a chronic ulcer on my foot that seems to be spreading. Its been there for weeks and its starting to cause me a lot of pain.  <response>: Based on your symptoms, I would recommend a few medical tests. We need to start with wound care management to make sure we properly clean and dress the ulcer. Additionally, we will perform a complete physical skin exam to determine the extent of the damage. We may also need to do debridement of the wound if it is infected. Finally, well examine your foot and consider traction, splinting or other types of wound care depending on the severity of the ulcer. In certain cases, we may need to do an excision or referral to a home health care service.
