Hi, Welcome to Health care magic forum.
As you describe, all the experience you had is common with severe stomach ache due to the vaso vagal reaction.
The diagnosis depends upon the site of the pain, where you had the pain.
If it in the upper right side may be related to the
gallbladder, liver,kidney. upper middle,it could be the gastric pain due to the ulcer, if in the upper left side may be the spleen, or
pancreas pain, gastric origin, left
kidney pain.
Middle, right side pain may be due to the urinarytract infection, stone in the
ureter,etc. middle abdomen pain may be due to the worms.
Left middle abdomen pain may be due to the
urinary tract infection,stone in the ureter, colon pain.
Lower right side pain may be due to the U.T.I, stone in the lower end of the ureter,
appendicitis. etc.
Pain in the lower middle part may be due to the U.T.I,
pelvic pain, rectal pain.
If it is left lower pain may be the U.T.I, stone in the left lower ureter, or colon pain.
I advise you to consult a surgeon for diagnosis and treatment. He will treat according to the site of the pain.
Wishing for a quick and complete recovery. Thank you.
