Your ECG and echo are normal,
thyroid and cholesterol are normal, and an
HbA1c of 4.9 rules out
diabetes. At 25 with a normal heart workup, that suffocated feeling in the shower and the fear itself are anxiety, not heart disease. The sole and calf pain fits plantar fascia strain with possible
vitamin D deficiency, and frequent urination often follows anxiety and high fluid or tea intake. Stop repeating heart tests, because each normal report calms you for a day and the fear returns.
Next Steps
Get
vitamin D,
B12 and haemoglobin checked once, do calf and plantar stretches with cushioned footwear, start 30 minutes of daily brisk walking, cut caffeine, and practise slow breathing for 10 minutes twice a day. Anxiety of this degree responds very well to treatment, so counselling and if needed medication will change your life. Come for an online consult with me and we will treat this properly instead of you living in fear.
