Hi,
I used to run 3 to 4 kms without any problem but from last six months if I run even 1 km(in morning) and breathing becomes faster I get headache in the evening.Just after running I don't feel any discomfort but headache returns around evening.
I did full body test and there is
vitamin D deficiency and
thyroid around 5 but no other problem.
Please advise.
Thanks.
