Hi guys from the past couple weeks I've been having really strange symptoms and I don't know what it is. I went to my doctor but she's just stupid and said it's stress. I feel nauseous, and dizzy like lightheaded. At times I'm walking and my head will spin. I also have like weird muscle pain in my legs and arms. I've been having an extremely high amount of tension/sinus/migraine headaches almost everyday. my eyes also feel very heavy and tired. I also have some stomach pain I don't know what's wrong and I'm really worried as what it is I've read around on the internet and have read about a lot if interesting things but not all the symptoms match up I'm scared that I may have a brain tumor or mieres disease or something (not sure if I actually spelled that right) but please help me and let me know if any one has had any of these types of symptoms.
