Hi, I've had yellow loose stools, which by late afternoon become very yellow and sometimes oily. I've been getting really cold during the day and extremme night sweats, not being able to sleep and my stomach is extremely swollen. Also have back pain, and as if something is stuck in my oesophagus. This has been going on for 6 days. Ive had loose yellow diarrhea on and off for month now, but has got worse since a week ago. Would really appreciate any advice.
