Hi, I was wondering if anyone else is in the same position. For the past month and a half, I feel like I am not getting a deep breath in and am constantly sighing and yawning. It started off as a pain in my bottom right rib cage spreading to the back. The pain has all disappeared but the shortness of breath is still there. I have been to A and E and had a normal chest x-ray and ECG, except that it showed scoliosis, which I have had since I was a child. It didn't show the curve getting worse so I don't think these symptoms are being caused by scoliosis. I have also had heart palpitations. I have had a ct scan and 2 MRIs of the heart which were all normal between 2019 to 2021 as I was getting palpitations then as well. The only thing abnormal have been my folic acid levels in January which were 2.7 and my ferritin levels of 25. At that point, my GP did not mention anything as this was all in the normal range but since I am trying to conceive and my folic acid levels are borderline I have started taking 5mg of folic acid. Has anyone else experienced this? The rest of my blood tests have been normal including thyroid and full blood count. It is definitely better than before but comes and goes.
