I'd suggest retesting as well, Dnester. I agree with Betty_Banana. I don't think it would be useless. Even if you did have the same diagnosis, at least you would know for sure. And if it was different, you'd be able to get the treatment you need and deserve. It doesn't hurt to try, right? What do you have to lose? I don't think meds would affect your diagnosis significantly, and even if they did, your doctors should know that and be able to get you a proper diagnosis based on the information they have. Please do consider it. Talk to your doctor about this and see how it goes from there. I hope things will get better soon. Feel free to PM me anytime. Let me know if I can do something to help you. Wish you good luck! Let us know how it goes. Sending many hugs to you
