Hi welcome to Healthcare magic forum.
Thanks for choosing H.C.M.Forum.
I started
with severe abdominal pain, no pain, severe in the left abdomen, around your ribs. last night you felt that some thing bit you on the back. The area is red and raised. You didn't take any new medicine or food.
It appears to be the neurological pain, cause may be
herpes infection, latter may proceed to watery
rash, followed by neurolgia.
Other possibilities could be
gastritis, and utricaria related or not related to the pain.
I advise you to consult a physician for diagnosis and treatment, to prevent permanent neurolgia, not relieved even after remision of the rash.
Wishing for a quick and complete recovery.
Best regards.
