I started having horrible tension headaches, migraines, "ice pick" types - you name it - all starting in October. They lasted until December - where they disappeared entirely - only to reappear on May, 9th. I went on a violent roller coaster at amusement park and received horrific migraines for the following month. I was recommended to see a chiropractor by my family physician in order to perhaps eliminate the pain and help with my back. I was skeptical, but my doctor insisted she "only did soft tissue work" and "doesn't snap your neck violently." Being the trusting person I am, I went in for it. I went to the chiropractor and sure enough, after awhile she started violently snapping my head. It hurt like mad when she was done, but she assured me the pain would subside and I'd "get used to the treatment." I went home sore and disoriented.
Later on that day, I noticed something bizarre: every time I walk upstairs - not down - when I step up with my left leg, there's a crackling sound in the base of my skull and in the back of my neck. It snaps and cracks every time I go up the stairs. Strangely enough, it's only triggered by the left leg! If I try using the right, nothing happens at all; there's no noise. However, if I use my left leg to go up the stairs, it snaps and cracks inside my head. It's too quiet to be heard by anyone else, but I can hear and feel it and it's freaking me the hell out.
On a side note, my left leg has also been sore and tender for the past while. Not sure if that's relevant, but I figured I'd give as much info as I can.
Please help me figure this out!
