I suffered a concussion on january 17, this year. Yesterday I had two balls on the back of my left ear. My gf didn't know what one was but told me the other one was a lymph node, It swollen and if I touch it I feel kind of dizzy, Did you find other ways to fix the lymph node? I don't own a trampoline and idk if my gf would even let me get on one with my concussion.Thanks
