Brief Answer: GPE.Hydration,Acetaminophen,Antiemetic & antibioti Detailed Answer: Hi, Thanks for using XXXXXXX I went through the query and understood your concern. High temperature with severe chills occur commonly due to 3 reasons, Urinary tract infection, Abscess formation (any size) any where in the body and finally due to malaria. For you, with your history of radiation therapy in the past and pain in upper part of stomach, the cause for the fever and chills may be in the upper stomach region, may be local wound/abscess or any infection. The darker urine after an episode of fever is due to concentrated urine. During fever the water evaporates and hence kidney concentrate the urine to retain water. No need to worry for it. So I advice you to get examined (General physical examination: GPE) by your doctor once and you require investigations like USG, haemogram and urine routine. This will help to pinpoint the cause for fever and chills. Till then you need to hydrate yourself well with plenty of fluids. For fever you need to take acetaminophen and take anti emetic drug like ondansetron. Antibiotic is needed and the choice of antibiotic depends of the site of infection (cause). These measures will help in managing your problem. Hope this information is helpful for you. Please feel free to ask any further query and I will be happy to help you. Wish you faster recovery. Regards

Brief Answer: Needs evaluation. Antiemetic, analgesic Detailed Answer: Hi, thanks for writing back. Be relaxed. The knot you felt during stomach pain/vomiting may be cardiac sphincter (gastroesophageal sphincter) or stomach (contracted stomach or any mass) or even due to the skeletal muscle contraction. The reflux movement can cause pressure on the sphincter and can cause pain. For reflux, the antiemetic drug will help and with the investigation of USG abdomen and pelvis we can find out if any mass present in upper abdomen that is feeling as knot. So the management depends on the report. You can take antiemetic with mild analgesic drug (NSAID). This will help for the pain and reflux. But you need examination and investigation once to rule out if any other underlying pathology. Hope this helps you in the management of your illness. Feel free to ask if any other related query. Wish you good health Regards
