Hello this is sneha, my father has recently recovered from covid now he is feeling dizzy and feeling head heavy while recovering from covid he had low sodium levels which resulted in bradycardia, now his heart rate is normal but he thinks that dizziness is result of either heart problem or varicose veins which he had from very long back and feeling heavy in the left leg, is there any chance varicose veins are link to dizziness and feeling head heavy, and he has noo symptoms of stomach pain or any ear infection.
