Im 23 years old, my body has been itchy and forming hives especially at night, my face swells in the morning and my lips too, my palms itch too and form tiny blisters, I feel like something is stuck in my throat, I get stomach ache after a meal and recently I passed out very dark stool. I suffer from constipation and bloating too. I was recently diagnosed with pelvic inflammation disease, uti and a cyst in my ovary. I was given antibiotics and pills for allergy which helped me but as soon as the pills were over I started breaking out in hives again, I was told to avoid proteins which I did but still I get hives. What could be wrong with me?
