Hey Sweetie,
This comment you wrote made me very happy for you "says im a healthy young pregnant woman."
I did the research for you so I would not advice adding the possiblity of this to your concerns, that is just my opinion. You just saw your physician and he would have picked up on this problem.
A transient ischemic attack (TIA) is a transient stroke that lasts only a few minutes. It occurs when the blood supply to part of the brain is briefly interrupted. TIA symptoms, which usually occur suddenly, are similar to those of stroke but do not last as long. Most symptoms of a TIA disappear within an hour, although they may persist for up to 24 hours. Symptoms can include: numbness or weakness in the face, arm, or leg, especially on one side of the body; confusion or difficulty in talking or understanding speech; trouble seeing in one or both eyes; and difficulty with walking, dizziness, or loss of balance and coordination.
This is good info for some people and should you ever have an attack as described above seek medical attention.
For now I love the "happy healthy young pregnant woman" diagnosis by you Doctor. The piched nerve also sound reasonable.
