Ok....it's been 18 hours and the Arnica Gel seems to be the ONLY thing that works!!! I didn't have any this morning, only the oral Arnica 200, so I took those and my headache felt a little, tiny bit better, but nothing like the relief from the night before. I called my son and had him pick up some Gel on his way home. I put it on my forehead and between my eyes and along my sinuses about 10 minutes ago and already the pain is almost all gone. This is the only product that has worked so far on this excruciating headache!! In the last 5 days I have tried everything from an entire box of Theraflu, Migraine medicine, Aspirin, Tylenol, Advil, Aleve, Peppermint Oil, Magnesium, Arnica 30c, Arnica 200ck, massage, salt baths......and the Arnica Gel is the only product that worked...almost immediately!
