I have a strange medical problem feel weak, fatigued, dizzy, chilled, and cloudy headed, terrible skin sores?

I’m a 34 year old female and I have a strange medical problem. I have frequent days when I feel weak, fatigued, dizzy, chilled, and cloudy headed (like I have a concussion.) Also, the past 2 weeks I’ve started getting these terrible skin sores. They’re big, swollen, painful clusters of small abscesses each with a pus filled, pimple like heads. There’s about a thousand heads on each abscess and I can’t pop them because the abscesses are too painful to even touch. Eventually they fill enough that I can pop them and when I do, there’s coarse black hairs inside. These may be unrelated symptoms but I’m fairly healthy and it’s doubtful I have 2 weird issues. What could this be?
