<s>[INST] My sister has gone to the doctor twice and had tests. Have not found anything but are treating her for diverticulitis. She has a lump in her stomach. Now she has bruises on her left side of belly, ribs and low back left. She is very tired. She wakes up then needs 2-3 hours of sleep. She has lost 65 lbs in 8 months but had a baby at the end of July. I don t have a lot of other details. She is thinking of going the hospital route this weekend to see if they can admit her and figure out what is wrong. [/INST] Hi, Dear,Thanks for the query to Chat Doctor. I studied your problem in depth and I understood your concerns. Treatment for lump in stomach-Your sister has recently delivered a baby. In this background the diverticulitis diagnosed by your doctors, needs to rule out the unresolved Uterine lump which needs second from ER Gone doctor and from ER Surgeon to rule out the diverticulitis with lump in abdomen. Other causes of the lump would be ruled out by the ER Surgeon. So take these pre-cautions before admitting to hospital. This advice is based on the facts from the history you give and needs further clinical check. So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you, but just ask a query to Chat Doctor and be comfortable to resolve your health issues. Welcome for any more query in this regard to Chat Doctor. Write good resume and Click thanks if you feel satisfied with my advice. Have a Good Day. Chat Doctor. N. </s>
