I think I may have a UTI. I do feel like I need to urinate frequently, with very little or no success. Also, I have a tingly numbness in my hands and fingers right during or after this need to urinate. A side note, I am slightly anemic and do take B12 supplements to increase red blood cell count. I ve not taken them recently though, because I ran out a month or so ago. Maybe not related, but relevant to medical history: I m hypothyroid. I was born that way, it was a very rare condition involving a total lack of chemical signal and the pituitary.
