Hello everyone I am a registered nurse and my boyfriend has been sick

Hello everyone I am a registered nurse and my boyfriend has been sick. All last week he had cold sweats, fever, chills, malaise, migraines and loss of appetite. I had him tested for covid, results still pending. He woke up Monday feeling great, but he noticed spots all over his body. I took him to the ED ( I wasn’t allowed in the room), they told him he had Lyme gave him a script for doxycycline and did NOT even take blood from him. In my opinion I do not think this is Lyme and it’s not scaly or crusty like ring worm. The spots vary in size and shape, they are on chest, legs, arms, and back. They are blanchable and they don’t itch or hurt. Some are a little raised and others are not, but all of them are soft. I would like some opinions.
