My husband has a large, a little bigger then golf ball size, lump sitting on one of his vertabraes at the back of the base of his neck. It is going down but he says it happens whenever he is doing weights that require him to put the bar on his back. I did the same movement with less weights and didnt have this issue. It s been three days now and it has shrunk, but it s curious because his lymph nodes in his armpits are currently swollen, we think due to the injury in his roataor cuff which is being looked into right now, but could it be related and should we be concenred. It does hurt him when it is touched.
