That's a really interesting observation! While there's no strong evidence in current research directly linking vitamin B12 injections to hive relief, it's worth exploring why the hives may have improved.

Hives from food allergies are often short-lived on their own — a single hive can disappear within 24 hours, though some cases take days or weeks to fully resolve. So timing could play a role here. There is one indirect connection worth noting. Bruising alongside hives can sometimes be linked to poor nutrient absorption (malabsorption). If B12 levels were low and affecting overall health, a boost could potentially support the body's ability to manage inflammation — but this is speculative.

Here are a few things to consider:

- Track your symptoms — Keep a journal noting what you eat, any supplements taken, and when hives appear or disappear
- Speak to your allergist or doctor — Share this observation; they can help determine if there's a real connection
- Don't stop allergy management strategies — B12 should complement, not replace, proven approaches like antihistamines or avoiding trigger foods

It may be a coincidence, or it may be meaningful — either way, it's definitely worth mentioning to a healthcare provider!
