I m concerned about discomfort in the inner part of my upper left arm. It is mild to moderately painful with concurrent numbness and tingling that extends to the tips of my left fingers. The numbness and tingling is the same as the feeling you get when something cuts off blood flow. I have had 3 cervical surgeries for multiple C-series ruptured discs in 1996, 2000, and 2003. Those were all causing symptoms in my right arm only. This is the first time I ve had any problems with my left side. The current symptoms don t feel the same as those I experienced with my right arm. The discomfort came on gradually over the past 3 weeks. I ve had no trauma or falls; I have had an increased level of physical activity in the same period, but the discomfort is most noticeable when I m sitting around in the morning. It doesn t feel muscular and my biceps and triceps don t hurt when I touch them. Thanks, Mark Nault
