Does your body give up when you quit smoking?

I quit smoking about 3 months ago. About one month in I started having one health issue after another. I’ve NEVER had health issues like this before. Between a tooth crumbling, to skin disorders, and female health issues. I just feel not well. I’m wondering if this is because I quit smoking, or if I’m 27 and my body is just done being happy!? If so how long will this last?
