I have a dull ache in my left arm, above elbow near the back. Noticed it yesterday evening and is happening again. I wouldn't say it is painful, but it is aching. I have a small hole in my heart which used to be checked every 2 years, but about 4 years ago they said we could check just every 5 years. I am 25 and 5ft4 weighing approx 52kg. I saw a doctor a few months ago as I have had short, sharp pains in my chest which are very uncomfortable.
