<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I am feeling a lot of pelvic pressure and have noticed excessive growth along with joint stiffness and tightness. I also have a lump on my knee that I am concerned about.  <response>: Based on your symptoms, it seems likely that you are suffering from scurvy, which is caused by a lack of vitamin C in your diet. This condition can lead to joint pain and stiffness, as well as a general feeling of malaise. Well want to get you started on vitamin C supplements right away to help treat your condition.
