I've been getting hives every night for the past 5-6 months. My skin gets really itchy and bumpy, especially around my hips, lower stomach, and the back of my hands. They go away by morning, but it's been happening regularly. I don't have any known allergies. What could be causing this, and how can I treat it?

It sounds like you're experiencing chronic urticaria (hives), which can occur for various reasons, even without an obvious allergy. Stress, temperature changes, or other factors could be triggering it. I recommend avoiding known irritants, managing stress, and trying antihistamines for relief. If symptoms persist, please consult a healthcare provider to rule out any underlying conditions or explore other treatment options.
