I can relate to your dilema... I did not have the chest pain but the numbness. At first the doctors thought I had carpel tunnel (sp) but no pain. Then I lost my ability to speak and that scared me. I was sent to a neuro and he showed me my MRI with all my white spots. Scared me to death. Most are on my right side and I guess that affects the left. I don't know the technical stuff, but he actually suggested I seek a 2nd opinion, which shocked me. So my husband and I are gathering info. and making appointments.
If you are unsure of your options or what your doctor's are saying, I recommend the same. It won't hurt!
