ok, so while laying on the couch my cat knocked over the lamp and it surprisingly hit my head hard in the temple region. This was about a week ago...I had a splitting headache for a few days, and just today my daughter and I were playing around and I got knocked on the same side (very innocently) and now I am tasting metal. The site is very sore still - I also had severe neck pains and some residual pain along the jawline for a few days after that which I just shrugged off. Should I be concerned? Most importantly is this metallic taste connected? Thank you.
