Help! Allergic reaction and itchy rash on my neck

I don't know what else to do besides go to the ER, but if you can't afford the ER (shits expensive af if you don't have insurance), antihistamines can help. If you think its being caused by a drug I'd stop taking it if you can (as in you don't absolutely need to take it) and see if it goes away. If it's a prescription drug I don't suggest stopping cold turkey unless you're a small dosage. I also wouldn't trust this advice 100% as I am not a medical professional, nor have I had an allergic reaction that I haven't gone to the ER for (if you choose not to go to the ER). Sorry this was long, I hope you figure it out and feel better soon ❤️
