My husband and I have been trying to conceive for over 1 1/2 years, We are seeing an infertility doctor. His sperm is good. I have been having issues with blocked tubes, and I just got checked for my uterus lining. My question is, I have a bone spur in my heel and I am going to the doctor next week. If I get a cortisone shot, will this have any side effects on us trying to conceive?
