Hi...just this morning, I noticed a burning sensation when I went to urinate. I have been urinating quite frequently. However, what has me concerned is around noon I started feeling shortness of breath. I do have a sinus arrhythmia and know what it feels like when my heart skips or adds a beat. It feels like it s on the verge of skipping but doesn t. I just thought it was quite a coincidence that all my symptoms start within a couple hours of each other. I have appt in the morning. Has me worried and concerned. I ve had uti s before but never one that caused shortness of breath. By the way I am 38 years old, female. I notice it gets worse when I stand and move around. It s constant though. No pain, I do have some cold chills which isn t typical for me. No fever as of yet. Could you tell me what this possibly be? Any ideas or anything I should mention to my family doctor? Thank you in advance.
