I'm not new to acupuncture, but I haven't had it done in a couple months. I had a treatment last night, and it felt amazing. Then, about 30 minutes after I got home, I rubbed my head and realized that my scalp on the left side of my head is completely numb! Not only that, but the place I go is closed on Sundays and Thursdays...so I can't call, which I wish I could because it's been almost 24 hours and it's still numb! Anybody know what this could be?? Is this dangerous?
