it quite possibly may be gallbladder pain. UGH i wouldnt wish that on the most evil of persons.
i cannot even describe to you the type of pain i had with gallbladder attacks other than "the type of pain that is so intense and so constant, that if someone were to attempt to touch me i would do them bodily harm"
i hope you are feeling better.
also, try homeopathic colocynthis 30C
