An hour and half after my 2nd set of botox a knot appeared then developed into pain deep inside my jaw/ear area a few hours later, directly in front of my ear, it is aggrevated by taking/chewing/swallowing. My neurologist was out of the office since the shot, but I had a GP check it for infection, ect.., they only found slight swelling and a painful lymph node in front of my ear. I attached a photo of where the knot formed and it is gone, but the pain and slight swelling is still there.
