I am a 43 year old female with a problem that I have endured all throughout my life. Since I can remember, I always had a burning pain on the left side of my body. The pain always starts from the left lower quadrant, and then the burning pain radiates to my left leg up to my left back side, to the left side of my neck, and to my whole face. Then I feel squeezing sensation in my left ankle. When this happens, I also feel pain traveling up from my right foot up to my right knee and squeezing sensation in my right ankle too. Sometimes with this burning pain (8-10/10) I have pain in my eyes, a burning pain in my tongue, and ringing in my both ears. I can have this pain for a month or up to 6 months and then the pain vanishes. After the pain disappears, I feel OK for a little while until the burning pain returns. Recently, I did not have this pain for approximately a year and then the pain came back 2 months ago with all of its symptoms. Now the pain in the left lower quadrant is worse, and I have burning in the left site of the body again. I feel like something is poisoning me when the pain is worst in this area, and then i have nausea but no vomiting. 2 weeks ago, I began to feel a sharp pain in in the lower left quadrant under the pelvis bone, and I felt nausea and burning pain along with numbness, which was intense to the point that I felt as if I was shaking and I was weak. When I am lying down, the sensation that I feel is less intense, but when I begin to do physical activity, I feel the burning pain again. When I was pregnant (I was pregnant two times), I experienced this burning pain all the time, and the pain became worse towards the end of the pregnancy.
I saw a neurologist, and I had 6 MRIs of my brain, a lumbar puncture, and a nerve study, but everything was fine. My blood work is also fine, except that I have anemia and vitamin D deficiency. So, I am looking for an answer as to what causes this pain.
