I have been having serious neck/shoulder pain for the past two weeks. It s been getting significantly worse and I plan to see a doctor, I believe it s probably my rotator cuff. However, last night the pain was so severe, I ended-up with such a severe headache that I thought I was going to vomit. I took some ibuprofen and the pain in neck, shoulder and head eventually went away. Today, I m sitting at my office and I was scratching my head and I noticed a pretty large lump(about the size of a quarter) on the top left side of my head, about two inches above my ear. I haven t hit my head at all and the lump certainly wasn t there this morning when I was washing my hair. I am now wondering if the headache I had last night wasn t related to my neck/shoulder issue but maybe related to this lump that just appeared out of nowhere??? I am 49 years old and typically very healthy. I plan to see doctor as soon as possible for the neck/shoulder pain but should I go to the emergency room for this mysterious lump? I am a bit nervous now. Thank you.
