Hi Dear !! Thanks for your query to HCM. Read and reviewed query. Based on facts of your query, You seem to suffer from- Post-partum Coccydinya with IBS D with PID. Changed Biomechnics after delivery, has inflammed sacro-Coccyxial joint. With Severe PID with accompanied IBS D- is giving a false sense that the Coccydinya is causing all this diarrhea. Its interelated and is caused by both the entities along with accompanying PID-pelvic inflammatory disease. Check for Claust.Difficile- due to overusage of antibiotics used for IBS D. Treats- No need of colonscopy. Try Bland diet with Yogurt helping 2 per day. Be Low in intake Volumes of solid diets for 1 week. Be more on Liquids with rice / bannana / smashed potato or smashed apple with honey. Use PPI like Normaxine-RT-Rabeprazole- +Clinidium-antispasmodics +Chlordizepoxide-antianxiety +Dicyclomine to treat anxiety depression and many accompanied central causes in post-partum periods. Supplemented with B12 / Folic Acid would recoup your condition very soon. Tab Dexona- steroid treats for Crohn s to be used meticulously if need be. Be on dietary and life style changes rather than steroids and antibiotics, irrationally, as you are lactating simultaneously. Don t worry for all this. Act like suggested. Hope this would resolve your health issues early. Welcome for any further query in this regard. Good Day !! Dr.Savaskar M.N. Senior Surgical Specialist and Thorasic / Chest Surgeon M.S.Genl-CVTS
