Thanks for posting your query.
At the outset your complaints seem to be unconnected. Lower abdominal pain
can occur due to a urinary tract infection
or in women pelvic inflammation.
You can do a urine microscopy to rule out infection. Drink plenty of fluids.
Check the skin over your breasts. Is there any rash or swelling? If there is a rash, you can try applying an antifungal skin cream. If there is any swelling it is best to see a doctor who will examine the swelling and decide if it needs to be further evaluated with tests like mammogram
Bad dental hygiene or gum inflammation
can lead to toothache. For relief of pain you can take some over-the-counter pain killer, but get tested by a dentist
to rule out cavities that need to be treated. Take a diet rich in Vitamin C
by including plenty of fresh fruits and vegetables.
Wishing you good health
