It sounds like your skin had a strong reaction, likely contact dermatitis, to the Veet hair removal cream. Since it has lasted a few months, your skin barrier needs gentle care. I recommend stopping any harsh products on your stomach. You can apply a thin layer of over-the-counter hydrocortisone cream twice daily for a few days to ease the redness and itching, alongside a fragrance-free moisturizer like plain petroleum jelly. Please consult a doctor or dermatologist for a personalized evaluation, as a persistent rash may require prescription treatment. You will get through this!
