Had dental abcess. tooth extracted. during work out felt very weak and got echo in the ear..did blood work ekg, and xray, good..ended pen vk yesterday?

All will be OK: How long ago was extraction? If within 2 days, taking it easy with workout would be reasonable. The clot formed is not fully "set" and raising heartrate/bp could cause dislodging it. This would cause a "dry socket", an uncomfortable situation. Penicillin is being used to kill the bacteria from the abscess. It will take a few days to resolve. Follow oral surgeons advice, and all should be fine.

Relax: I do not see a timeline here so don't know how long from surgery to working out but it sounds like you should take a little time off working out to let your body heal. You should verify this by going to your doctors.
