What Causes Grinding Painful Sounds Inside The Skull?

Hi, I m 27 years old, 240 pounds, have severe fatigue, inability to lose weight even though I spent the majority of my life at average or below average weight and in very good condition. I have digestive issues that mimic stomach ulcers along with severe diarrhea and vomiting that sometimes contains blood for which I take Protonix. H. Pylori negative. I have pretty severe joint aches, specifically in my feet, hands, elbows, ankles, and knees, severe fatigue, strange hair growth...lol...lichen something on my tongue, high blood pressure ONCE and then normal everytime after that and high triglycerides, I m sure weight related. So NOW I ve been noticing this very strange fizzing, crackling sound that I can also feel that starts right at the base of my skull and moves upward into my head that s been going on for a year (that I ve noticed). Sometimes it s accompanied by a really strange pain, not AWFUL pain, but mild pain that shoots up from that area into the back of my head that lasts for about 30 seconds to a minute. I ve been going to the doctor once a month trying to figure all of this out and I m getting very frustrated. All of this started, mostly with the hair growth on my chin, breasts, and legs, during my second pregnancy. I ve had three children. I currently have an IUD which has been in place for 2.5 years. Oh, I also have high white blood cell count and have for about a year to a year and a half, high sed rate, and a temperature of 101 F constantly. Can you help me? What could this fizzing sound be and is it related to ALL of this other nonsense I ve been dealing with?
