I guess my problem started a few weeks ago with headaches that lasted for 5 days. The headaches weren't that painful, but one day me left harm went numb so I went to the ER and got a CT scan of the head, which came back negative. I also got a MRI of the head and it was negative as well.
Then, I started to develop some minor back pain in the spine. I thought this was a bit odd since I am only 21. I got an MRI of both the lower and upper back and that came back negative. Now, the pain is mostly gone but I still have strange sensations in my spine, which often keep me up at night. I also sometimes get dizzy.
Can you give me some ideas about what this is? I am pretty sure there is something wrong with me, but I already had MRIs so I don't know what else I can do.
