My niece has the following symtoms and I am wondering if she needs to go to a diagnostic center such as Sansum Clininc. Her symptoms are: tired, listless, sleeping a lot (not rested when wakes up); red rash on neck, blotchy red spots on upper chest, loss of appetite, swelling in hands and feet, feet feel hot, headaches on left side of head (suffers from migraines but have increased in frequency an intensity over last 2 months), feels dizzy every day. She just turned 18 and I am worried about her. Help!
