Hello, I am a 33yr old woman who is a bit overweight & my doctor has found 5 lumps on my thyroid & I am borderline diabetic. Yesterday while relaxed, my lower left arm and hand went numb and I had a tingling rush to my head & felt faint. While I haven't had my thyroid checked yet & my cholestorol is fine I am wodering if this could be early signs of anything serious. I was checked by paramedics & everything was normal besides high oxygen levels from my getting worked up about what was happening and panicking a bit & a little high blood pressure. If anyone has had these symptons or knows what could be happening to me I'd gladly appreciate your knowledge.View Thread
