Thanks for posting your query.
Stomach ache after taking coca-roasted almonds may be due to acute gastroenteritis
or simple gastritis
Do you have water shit/ fever/ spasmodic abdominal pain/ vomiting?
If yes, then there is chance of gastritis and you should consult with physician and gastro-physician and should go for proper antibiotic treatment with proton pump
inhibitors and antispasmodics.
If no, then you should go for endoscopy after consult with physician.
Regarding your diverticulitis
, if you are getting fever with abdominal pain then it may be acute in nature and colonoscopy
is contraindicated as there is risk of perforation.
You should take high fibrous diet with plenty of water.
You should also take anti-inflammatory medicine for decreasing inflammation.
