What sort of pain do you get in your foot?

reason for asking is that I have had a terrible pain in my foot for 3-4 months now.. Before Xmas the Dr told me I had some sort of inflammation but due to breastfeeding I couldn't take anything so I just bandaged it at night when it was particularly sore.. I went back this week as it is not getting any better and I have to get an Xray as well.. Dr said possible arthritis but is unsure..
