Hearing aid in gray case with blue trim

Yesterday around 3:15pm I lost my Phonak hearing aid in a small gray carrying case with blue trim. I was walking from the Bank of America Stadium area on South Boulevard toward the coffee stand near the stadium entrance in Charlotte when I think I dropped it. The hearing aid is white with a tiny blue dot near the volume control, and there's a light scratch along the top edge. The gray case has a circular sticker on the lid with the initials 'LT' and a navy blue zipper pull—it's small but distinctive. This device is essential for me; it's the only way I can hear clearly since my surgery, and I really need it back.
