I've been wearing my Garmin Forerunner 245 for 5+ years. about 3 weeks ago I noticed some itching on my wrist around the watch face. What started as a small red mark turned into a large red rash. It feels like a burn but itches as well.... I didn't wear my watch for 3 weeks, let the spot heal completely before putting my watch back on. I put it on for less than 12 hours and my "burn" came back with vengeance. Could it be the charging port prongs burning me? Has anyone experienced this lately?
