Detailed Answer:
Dear XXXXXXX
It seems that you are suffering from itchy
hives that come and go with some skin swelling, that is referred to as urticaria.
Urticaria is a skin condition with raised, red, itchy lumps - rather like nettle stings. It is also known as hives. The lumps can be very itchy and distressing, but are not necessarily dangerous. Each crop of skin lesions usually lasts less than a day, but fresh crops can appear one after the other. Episodes. Those that go on for more than six weeks are called chronic urticaria; shorter attacks are called acute urticaria. Acute urticaria is common - around 20% of the population has an episode at some time in their life.
Causes are unknown in most cases - although infections, drug sensitivities (in your case, antihypertensive drugs may need to be reviewed to see if any change in medication matches with the onset of symptoms),
thyroid abnormalities (antithyroid
antibodies), iron or Vit B12 deficiency and underlying autoimmune diseases such as
diabetes can make it difficult to manage. I would urge you to discuss with your doctor about the aforementioned conditions. Your doctors will know individual test to ruled them out.
Further, you might need long acting antihistamines for 3-6 months. And occasionally stronger drugs such as ciclosporin may need to be contemplated.
A picture will be helpful if you can upload. But I hope I have been able to explain the situation to you.
Best Wishes.
