Infection of the cervix

Has anyone ever had an infection in the cervix? I'm going on 5 days of extreme pain and swelling and I can not find any relief. I was given a shot of rocephin and am taking macrobid at home. Only pain relief I can do is tylenol and azo. Please if anyone has ever gone through this I need positive experiences! How long till it went away and what helped?!?! I haven't been able to go to work for 2 sags because the only way I can get comfortable is my propping uo my lower back and getting pressure off my cervix! Help!!!
