Leir said he had removed about a dozen implants from people's bodies and claimed they were devices that emit radio signals..

Swelling from SVC syndrome is due to blood having trouble draining back to the heart, so the swelling involves the entire face, neck, and upper chest, is red, is worse in the morning after lying down for many hours, and may get better once the person is standing up for a while.
As for a red face, this can have a wide variety of causes including rosacea (a skin condition that may also cause swelling and sores), allergies, inflammatory conditions, fever, and sunburn. Medications (including some used to lower blood pressure) can also cause a red face as a side effect. However, one thing that's very unlikely to be behind your red face is high blood pressure. So that's one less thing to get hot and bothered about.
