The embargo doesn’t cover medical supplies and Cuban buys what medicine and medical supplies it has mainly from the US. The embargo also doesn’t cover food.
Cuba also does a lot of trade with China and Spain but has relatively little to actually sell because the state controlled industries are so unproductive. Cuba also has the least productive agricultural sector in the Caribbean, despite being the most productive before the revolution.
The embargo is no excuse it doesn’t cover other countries, and Cuba has always had European trade partners. In fact they received free oil, agricultural equipment, and technical support from the USSR, and later free oil from Venezuela until a few weeks ago.
The Cuban economy today is a shadow of what it was before the USSR fell apart, which makes it a moot point to claim they are dysfunctional despite foreign support. The Soviets successfully managed to keep Cuba afloat. Not that that constitutes a ringing endorsement for the Cuban system.

Man, sounds like life before the revolution must've been super awesome! I bet everyone wants to go back to that standard of living.
