Muscle pain , fatigue , dizziness

Hello.I am a 34 year old female. I started with issues when i was a teenager. I had digestive issues. Never did anything about it because I thought it was normal. I was always constipated. I went into my doctor because of bad stomach pain he said I might have IBS. Later I had kidney stones. Had my parathyroid removed. Joint and muscle pain..was told perhaps i had lupus or rheamatoid arthritis. But all blood work was normal. Now I have muscle pain, fatigue, dizziness, pale lips, dull rib pain, numbness or arms and legs, tingling, sensation of swelling of knees and brain or head, anxiety, sensitivity to sound, weakness in arms and legs, mucous in back of throat and stool, feeling of fainting. I have had numerous blood work. The weird thing is that these symptoms come and go. What does this mean? I am tired of being treated like a lab rat to be told all my blood work is normal...and I still feel all these odd symptoms. I know this is not all in my head. thank you
