- Hi Martyn, I was biten by three leeches last Friday in Victoria as I went bush walking up Mt.Macedon. I am wondering if leech bites are linked to generalised muscle aches and pain in the body? This is what I've been experiencing for the past few days (since Wednesday). Also, nausia. My dad is a doctor and found your website. It could be something else but we thought it was worth the ask. Kind regards, Katrina.
