20 year old female. 2 months ago, I began experiencing sudden tingling all throughout my body. It was incredibly intense, as though ants were crawling all over me--that skin crawling sensation. I couldn't even sleep it was so strong. Gradually, the intensity decreased, but it still hasn't gone away, and I've developed new, equally random-seeming symptoms. I have an intermittent, but always painful to the touch, sharp pain on my lower right abdomen/pelvis. It sometimes feels crampy, and at one point felt like burning. I also feel as though my chest/ribcage area is burning/inflamed and everything seems to just ache all over, sting, or tingle, particulary at this point my back near the ribcage, legs, and feet. I've had a pelvic ultrasound, stomach x-ray, and stomach CT with contrast, as well as blood work, and all is normal. I'm very frustrated and honestly, scared. Can you help me?
