What Causes Mouth Sores, Exhaustion, Raynaud S Disease, Sore Joints And Muscles?

Hello Dr Rynne, My 26 year old daughter has the following symptoms, and has had them for about 10 weeks. They have become increasingly more severe as the weeks went on. She has gone in for blood work, and we are waiting for results. She is not a big drinker, does not smoke or take drugs. She has a history of tummy problems and has removed gluten from her diet, but has not been tested. She has Raynaud s disease, but is otherwise healthy. Symptoms; extreme exhaustion, sore joints and muscles, sore gums and mouth sores, getting sick after eating. So tired, she falls asleep on the toilet, and can barely stay awake at work. Also, short of breath and can hardly do anything. I am very worried, thank you for your thoughts. Barbara (mother)
