Panic: Fear or panic leads to release of adrenaline which causes fight-flight response, leading to rapid heart rate, rapid breathing & sweating. Rapid breathing causes drop in carbon dioxide in lungs then blood, which leads to shifts in blood ph (hydrogen ion concentration) leading to dizziness. Another cause is adrenaline leading to narrowing of blood vessels to brain, hence less blood flow to head.

Acne Therapy: Acne treatments work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection, reducing the inflammation or doing all four. With most prescription acne treatments, you may not see results for four to eight weeks, and your skin may get worse before it gets better. There are topicals like ziana and epiduo and oral medication like solodyn (minocycline). See your dermatologist.

Poor blood flow: The balance centers of the brain depend on good blood flow to the brain. If the heart is beating slowly or is not pumping enough blood into the brain, you will feel dizzy. First is to lie down so that the blood flow does not have to go uphill. Next is to lift the legs to be sure enough blood is getting into the heart. If the brain does not get enough blood flow, you can pass out and fall.
