I had a sudden sharp pain in various locations around my abdomen.  Then, I felt my lower arms and hands tingling and numb.  Then my hands started to contract to where all my fingers were pushed together involuntarily and I could not move them.  I started to feel the tingling in my feet as well but then it started to subside.  After awhile, I started to gain the control but my hands still feeling kind of weak. What could be the reason?
Hi. Thanks for your query and an elucidated history. The pain in abdomen and then the tingling and spasms of your hands and feet are suggestive that you have an attack of reduced calcium in the body. I would advise you to get your blood electrolytes tested and get corrected with a combination of vitamin D and calcium an appropriate dosage. Also, to get the hormone studies of the parathyroid glands as well as a high resolution ultrasonography of the neck for parathyroid glands. If there is an adenoid or so you have to get it operated.
