### Patient: Doctor, I have this lump on my knee and I am feeling very fatigued. I am also experiencing pain during my pregnancy and have been having pains in my ankles and face. Any idea what could be causing all these symptoms?
### Doctor: It sounds like you may have Leishmaniasis. It's a disease caused by parasites that are transmitted to humans through the bites of infected sand flies. Symptoms include the development of skin lesions, fever, weight loss, and an enlarged spleen or liver. The lump on your knee could be a skin lesion caused by the parasites. You should get tested and treated as soon as possible.
