[Skin Concerns] My skin has gone from hassle-free to incredibly dry, ultra-sensitive, incessantly itchy, and over all problematic in a matter of months. What could be causing it and how do I fix it?

Beauty Tips For Body Care
Not sure if this is the right place for this but I need help and I don't have the money to see a dermatologist, so here it goes. I have slowly but surely been developing the itchiest skin on the planet. There arent really any bumps, just itchy skin. Not just on my face, but over my entire body. I've gone to my regular doctor and I don't have scabies, bed bugs, impetigo, or anything contagious or pathogenic. What my doctor suggested is that I've developed allergies, which he said can happen at any time. I've essentially gone from having normal skin to developing super sensitive skin and it's driving me insane. I've been trying, through process of elimination, to figure out what it is that I might be allergic to and I've narrowed it down to multiple things.One is something in laundry detergents. Growing up, my mother always used Tide. This is an absolute no no for me now. I have found that using free and gentle laundry detergents reduces the itching, but doesn't entirely eliminate it. Dreft baby detergent is honestly the best, but it's so damn expensive for so little.Another is my body wash. I can no longer just grab any .99 cent body wash and be on my way. I've found that Aveeno Deep moisturizing body wash works nicely, but still doesn't fully quell the incessant itchiness.Also, lotions. I absolutely can't use anything scented. Some scented lotions feel like they're slowly incinerating my skin. I've begun using pure coconut oil and it works great and is very soothing.Last, but certainly not least, and possibly the most allarming, water. Perhaps I just have harsher water in my new apartment than any other place I've lived, but simply rinsing my hands in the sink leads to them becoming incredibly dry and itchy. It doesn't have the same effect on my son or boyfriend. I don't understand.So here are my questions: A) Has anyone else ever experienced this sudden change in their skin? Is it a common thing for a person's skin to go from not sensitive at all to being highly sensitive and irritated by almost everything?B) If I have developed allergies, what specifically have I developed an allergy to? Is there a specific chemical or ingredient that laundry soap, body wash, and lotion all share?
