I don't know which city you are talking about but If you are able to get away for at least a week to the mountains I would recommend that you try that. I'm in the Los Angeles area and within a couple of hours you can be somewhere in the mountains that feels like a whole different world. Once you get away, see if symptoms improve. Try go breath better quality air, go outdoors and take a stroll through the woods, go camping etc and only turn on your cell phone when you need it. Keep it off at night, try to stay in an environment with few distractions and few electronics.
Depending on how it goes, you may want to leave the big city. If the health issues go along with you no matter where you go, then seek medical attention, look up metal toxicity tests and things like that. Improve your diet. Give your body the best chance to heal itself and trust in the Lord.
God bless you.
