For the last few days I've been getting a bit of pain in my left armpit, but last night it got so bad I had to get out of bed as I couldn't sleep. I thought it had cleared up, but it seems to be coming back with a vengeance... I'm getting pins and needles in my left hand as well, and the pain is sometimes also in my elbow. Google doesn't know wnything about it, have any of you ever had anything similar? I'm guessing with the pins and needles there could be a trapped nerve somehere, and I've also just had a small bug, so I guess it could be inflamed lymph.
