Urinary tract infection
Thank you for the query.
Your symptoms indicate urethra
infection and possible bladder infection. When you are sitting, you put pressure on urinary bladder
and urethra. You may also have frequent urinating, trace of blood in the urine, lower abdominal pain
I suggest you to visit a doctor and have urine analysis. Antibiotics seems necessary. You should also increase mineral water intake and start cranberries supplementation.
Hope this will help. Feel free to ask further questions.
