I would suggest that you go to see your primary care doctor
about this issue right away. The symptoms that you are describing include discomfort with urination ("tickling sensation"), frequency of urination and cramping in the lower abdomen. All of these symptoms are most likely to be caused by a urinary tract infection
Urinary tract infections are a very common problem in women, with many women getting these infections on a yearly basis or more frequently. Generally speaking, they are not a major problem and can be easily treated with prescription antibiotics.
However, it is first necessary to have the diagnosis confirmed by your doctor. In addition to a physical examination, your doctor will likely want to perform some basic urine tests. If the diagnosis is confirmed, they can prescribe the necessary medications for you.
In the meantime, if you develop high fevers or severe back pain, these could be symptoms of a worsening infection, and you should not wait to get in to see your doctor. Rather, you should go directly to an emergency room for a more rapid evaluation.
Contact your doctor right away! I am confident that they can diagnose and treat this problem for you promptly.
