Around 3:00 am yesterday morning I started feeling a dull pain, mid-abdomen, L side, worsens when I inhale. Then this morning, in addition to the above symptom, which has persisted, I am having numbness, tingling down my left arm to my left hand along the left edge, with coldness in this hand compared to the other one. Not even sure these two symptoms are at all related, other than laterality. I m not sure what may come next and I do not want to wait to find out. Your thoughts?
