### Patient: Doctor, I've been experiencing some muscle pain and headache, and I also have a lump in my arm. I'm also feeling some congestion in my chest and my foot and toes are swollen. What could be wrong with me?
### Doctor: It sounds like you may have syphilis. Syphilis can cause muscle pain and headaches, as well as lumps or masses on the body. It can also cause chest congestion and swelling in the feet and toes. We'll need to do further testing to confirm the diagnosis, but we need to begin treatment immediately.
