Occasionally I suffer from periods of dizziness.  These last only a few minutes and the world seems to spin.  Afterwards I feel fine.  The dizziness I have experienced on and off for the last 3 years, but recently I have also been getting a tingling sensation on the inside of my arm.  It feels as though something is under the skin wriggling around.  Its not painful, but noticable and feels this way for much of the time. I was wondering what it could be?  There is a history of neurological issues in my family.  My father has cavernomas and now has been diagnosed with MS and my son also has also had surgery for cavernomas.  Could this be what is causing my discomfort (I assume I also have cavernomas).  Thank you.
Hello! Welcome on Chat Doctor ! The episodes of dizziness could be related to an inner ear disorder. While the tingling in your arm, could be related to a pinched nerve or a brain lesion. Considering that you have had a history family for multiple cavernous, I would recommend performing a brain MRI study. An EEG would be necessary to exclude partial epilepsy seizures, which can mimic this situation. Hope you will find this answer helpful! Best wishes,
