Hello Doctor, I have vertigo symptoms. I feel like my head is spinning/dizzy and sometimes some numbness in jaws. I had costochondritis and ruled out cardiac problems with all diagnoses like ECG, Echo, TMT and CT angiogram. All tests were normal. But  I don't know whether it's vertigo or not. All these started when I donated my blood last time in Aug 2023. My head feels like heavy/spinning and my balance will get affected by that time. For the last one month I'm feeling more so Visited GP and he prescribed vertin 8mg for 7days. But no improvement. Please help me ( I work with a computer for long hours and I had sleep disturbances from last July 2023 as I have a baby girl)
