Hi for 4 days now i have been having pain in my stomach/lower abdomen and back. the pain is constant.. I find it hard to sit at my desk at work as i have an office job... originally the first day of the pain i woke up out of bed and thought i pulled a muscle or a nerve.. but i still have the pain. i cannot pick up heavy objects (i.e my 1yr old son). Last week i can remember i felt dizzy for a few minutes like i could of fainted but not felt faint since. Also i am a smoker and have been doing a lot of coughing, but i have quit smoking so far for just over 2 days as i am constantly coughing up phlem. Also this morning while i was getting ready for work i had to stop as i had an agressive shooting pain in my lower abdomen. I have no idea what it could be? Its a very achey but severe pain.. i dont know if this will make sense but if it feels like a heavy pain like being 8 months pregnant carrying a weight.. i am on contraception pill cerazette.

Hi ! Good morning. I am Chat Doctor answering your query. From your symptoms specially the feeling of fainting with abdominal pain and being sexually active, I would suggest you to see your family physician/ER of the nearest hospital for a clinical examination and related investigation like a CBC, a urine routine/microscopic/culture sensitivity test to rule out UTC, serum Chat Doctor estimation, and an ultrasound abdomen to rule out an unsuspected intrauterine/extrauterine pregnancy. All the precautions including birth control pills are not 100% foolproof in protection against a pregnancy. And I would like you to report to your doctor at the earliest possible time to avoid any complication. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
