I recently discovered a lump on my body and immediately began researching a bunch of cancer and tumor related things.Even against the advice of my mother who has some medical experience and she checked it out and told me I was fine and it was probably lipoma. That didn't help me though. I stayed up all night "researching " Lately Ive developed these odd sensations like my head will feel cold or my back will feel hot when Im laying down. Ive seen a nurse practitioner and she said something similar and told me Im fine . Yet Im still feeling these things Anyone have advice on how to calm down.
