Can Breastfeeding Be Continued After Taking Steroid Shot For Sinus Infection?

Need tx for sinus infection that are ok for breastfeeding mothers. Don t want to reduce supply so can t do sudafed. Mucinex hasn t been studied. Sinuses are completely blocked, both ears hurting and also throat. Will go to Dr. tomorrow, but want to make sure what he prescribes is safe for me breastfeeding. Is it okay to get a steroid shot? I have been doing sinus rinses (not doing much since it s still blocked), drinking hot tea, diffusing essential oils, and this has helped some but not enough. Can t even speak it s so bad.
