I experienced the free health care in Cuba. I was having some lung/breathing issues. Rather than 'tough it out' and hamper experiencing Cuba at my utmost best, the hotel's on-call doc and nurse came to my room. I was diagnosed with lung and ear infections and given antibiotic, candy (throat lozenge), syrup (expectorant), and pain relief. The doc was free but I paid $32 CUC (about $33 US Dollars) for the meds and gave a $3 CUC tip (expected).
