I was admitted into the hospital due to a severe headache, neck pain and back pain. They thought it was an anuerysm as they found blood in my spinal fluid and thought there was blood in my brain. Several MRIs, CTs, CTAs, Spinal Tap and other test were done and they all came back normal. After 10 days of being in the hospital I was discharged only to be readmitted 4 days later for severe dizziness, so dizzy I can't walk. The same test were ran again and nothing was found. The doctors don't know what to tell me. This is the 3rd hospital that I have been to. Although the headache has lessened it has never gone away, and the neck and back pain, and dizziness continue to be there. They will be dischared from the hospital on Monday. What is wrong and what should I do now?
