mirena -stabbin pains, dizzy spells, empty feeling..

Hi,
Welcome to ehealthforum.
It is difficult to comment on the symptoms that you describe without examining you. The pain and spotting after intercourse could suggest possibility of infections, erosion, injury etc. The symptoms of headache, dizziness, increased thirst, frequent urination could suggest chances of pregnancy. The sharp stabbing pain could also suggest possibility of endometriosis, adenomyosis, pelvic adhesions, PID etc. The exact cause can only be made out after careful evaluation. Consider visiting your doctor/gynecologist at the earliest for thorough examination and further evaluation to look for the underlying cause. Get started on treatment as indicated by examination findings and investigation results. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. If infective cause is detected, get your partner also treated simultaneously, and avoid having intercourse while being on treatment to prevent chances of re-infection.
Take care.
