Sudden Weightloss, Fatigue, Nausea, Pain In Neck And Head. History Of Purple And Red Spotty Rashes In Thigh. Blood Test Normal. Suggest

Hi, I'm 24 years old, 5'3, and I weigh 132 lbs. I recently lost 6 pounds in 2 weeks without trying. I have been feeling fatigued, nauseated, the left side of my neck hurts sometimes, I've been getting sharp pains on the right side of my head, and I have noticed bruising on both of my legs. About 1 month ago I noticed what looked like a rash of purple and red spots on my upper left thigh. The night before I noticed the rash my legs were very much in pain. I have been feeling out of sorts since last November when I first got sick with a tooth infection, but I had the tooth removed and the infection cleared up. Since then I have gone to a doctor for blood work and that came back normal. I have days where I feel fine, but other days it's hard for me to get out of bed because I'm so tired and lately the nausea has been affecting my apatite.

Thank you for your time.
