I'm a 21 year old female that and I have lately of the last couple of months had quite a few similiar sympotems to that of other people in this forumn. It all started about 4 months ago, when I was due to go on my first aeroplane trip to QLD with my Boyfriend, the week before i started getting pins and needles in my hands and feet and occassional lightheadness that caused the feeling that i was going to fall and the feeling of unsteadiness, on the day before the trip I ended up at the doctors with chest pain and panic attack feeling, in tears. The doctor tested my heart and blood pressure and informed me that everyting was ok. I then went to the doctors a week later and got a referral for a blood test in which it was discovered that I have low iron so was then put on iron tablets. About two weeks later I was still experiencing the same symptoms, so went back to the doctor and was told that I had low B12 and was perscribed B12 shots to get injected monthly. About a week or so after that I ended up in the emergency room with chest pain and a numb feeling in my left arm and pins and needles in my left hand and a numbess in my left cheek. In which I went through all the same tests and was told I was ok and that I had anxiety, I went to the doctors after that and got a referral to see a Neurologist, in where I got a MRI done on my brain and neck to see if there was anything going on up there, but again the test came back clear. After this I didnt experience any abnormal systems for awhile so i let it go for awhile and I have now been experincing a pain in the left side of my chest and arm, Im not sure if it the anxiety or something else.. anyone have any suggestions?
