I had an extremely difficult pregnancy on my 1st child having suffered with SPD. I was wheelchair bound and in agony. This didn't go after I had my son and 2 years on I am still in a lot of pain. My mobility has come back but the pain is still awful. I have had 2 cortisone injections to the coccyux which has helped hugely. I feel I could cope with another pregnancy if I felt like I do with the injections so my question is.... Can I have a cortisone injection to my coccyux before I get pregnant? Will it be safe to conceive with the steroid in my body? It lasted 10 months last time so would be amazing if I could have it. Any replies would be much appreciated
