Have an uncle who informed me he had an episode this morning. Does have heart problems and some back problems. Said he bent over to turn a small heater on this morning and describes the following symptoms.

Had some dizziness yesterday, this morning had a major ordeal, after bending over to turn heater on, the room started spinning really hard, I fell against the door jam and held on. felt like I was on one of those spinning rides but not in a good way. I went to lay down and had a couple more times when it felt like the bed was spinning and I looked up at the ceiling and it looked like it was rocking back and forth.

He said he was going to go into a clinic this morning, does not have a general practitioner. I am wondering if he should coordinate some of his care with an internist? But also curious about possible causes for the symptoms above. He is 69 years of age.
