I am a 42 year old stay at home mom with six children ranging in age from 8 to 21 years of age. I am 5'2" tall and weigh 145 lbs. Over the last 2 months I've been feeling a sudden rush in my heart followed by a couple of very hard heartbeats immediately following. I am also waking up with my right arm completely numb. I can shake my hand out a few times and my arm will start to tingle and the feeling comes back. This morning, however, I was awakened by the ache in my arm and it took about 20 minutes for me to get the feeling to come back. I have had a very dull ache in my arm all day and I'm starting to get concerned that this may be something I need to watch. It only affects my right arm and shoulder.

Any suggestions or insight would be appreciated.
