I'm 24 years old. Around 7 days before I was having nausea and had vomited then I was feeling okay. But after that I developed constipation for 2 days and very pain in stomach also there was voice coming from stomach so I took lactulose solution and the stool came after that but it was all dry and had mucus like white substance in it. Also there was pain in uppermost part of stomach 3-4cm above bellybutton. Pain was there almost all the time during the day. One time pain was on the left side of stomach. Then after that dry stool problem was gone and I was having more normal stool but with more frequency and before passing stool there was also pain in lower abdomen and during passing of stool also. Gradually the frequency of the stool decreased and came to 1 time a day but till today also i feel pain before feeling of passing stool and during passing.also today I saw musucs in stool which came first then all the stool was norml. I dont have fever or any other symptom no blood in stool.
