Good evening.About 2 months ago, I started to experience a pain in my left arm. It lasts about 30 seconds, and feels like someone is sticking a hot needle in my arm. It s always in the same place (inside upper arm and just below my bicep, but just above where the joint/veins are) These attacks can happen over a dozen times a day, but more noticeable at night, when I m relaxing.I m male aged 45.Thanks Shane.
