About 3 weeks ago I found a lump on the proximal humerus in my left arm. I had this ache in it, sort of like you feel when you have the flu. It didn't last too long, but enough for me to notice it. When the lump is touched it doesn't really hurt, maybe a tiny bit tender, but I get aches and pains in the area of the lump. Sometimes my arm feels tingly and heavy, as if it fell asleep when it hasn't. It's hard to lift up my arm or to use it. I'm starting to get pain in my shoulder, and left clavicle. I'm fatigued and dizzy, very very dizzy. I can fall asleep anywhere at any given moment. I've also been feeling really hot at night. I have a doctors appt on June 2nd, but I just was curious what others thought.
Thanks in advance
