Yes, thank you. I have a sore spot under my right arm & some slight shoulder pain. It looks as though under my right arm is swollen compared with my left. Also, for the past 6 months at least I have been woken several times a night with pins and needles and/or numbness in my right hand/arm. It may be that I have a tendency to lie on that side and am compressing my arm? (I can only sleep on my side as lying on my back causes sleep apnea & I can t breathe) however, sometimes I also have the pins and needles in my left hand/arm, but more frequently on my right. What could be causing these symptoms?
Hi, It sounds like there is a mass lesion in the right axillary region that is compressing portions of the brachial plexus causing the symptoms you describe.  The most common sort of problem in this area is an abscess referred to as Hi Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further.
