Expired licence?

My job entitlement expires tomorrow 11 Nov .due to a problem at my local gp ( doctor shortage )i struggled to get a medical appointment.I eventually got one yesterday with d4drivers .knowing I was out of licence i booked a week’s holiday for this week while DVLA process my application. My problem is , I have sleep apnea DVLA are aware of this,however I expect they will contact the hospital to get confirmation that the apnea is controlled ,delaying things. My question is ,Can I drive in the meantime ? Or just i wait until I get my new licence in my hand. Thanks in advance

If there is a DVLA medical issue then what usually happens is that they send you a letter letting you drive but send you free of charge to one of their approved medical places near you

Thanks for the reply,was beginning to think I would have to spend time serving customers in the yard .
