Hello Doctor, I feel there is some sort of blood circulation issue in my body but not able to diagnose yet. I have visited multiple doctors till now. Complaint is that when i walk i feel imbalance , like someone pulling me either to left or right. Also when i turn around , walk fast or climb staris sometimes i noticed my saturation drop till 90 and restores back to 98-99 . I did chest xray, ECG, 2D Echo, MRI of brain and spine which is normal. Visited eye specialist and also ENT this is also normal. In march i did CBC test and my hemoglobin was 15.6 and RBC was 5.08. I repeated test on 11th march again and now hemoglobin is 14.4 and RBC is 4.73. So all that i could suspect if there is any circulation issue in my body. Pleaze guide me on next step to be taken and tests to be done. I just want to rule out the cause.
