Do everything you can to get a hold of medical. Call/email every day if you have to. Call your hr rep to complain if they're not getting back to you. I also got held up due to medical cause of my ekg but they never said anything to me. I only found out about it cause my hr rep called me to ask when i was going to resolve my medical issue and I was like what are you talking about? My hr rep wound up sending them a nasty email and they finally emailed me after that.
