I am sorry to hear about the pain you are experiencing. Non-narcotic pain control is a great question. The main prescription medications used in pain control such as Oxycodone, Percocet, Vicadin, etc are all opiates and are also highly addictive.
If you remove pill forms (opiates) from your pain control...there are alternative methods of pain control such as acupuncture and Chiropractors. You should always consult your physician before removing yourself from narcotic pain control due to the severity of withdrawals.
Under the circumstance that you have back issues, having a baby will also put severe weight on your back and may not be suitable for you. Have you talked to your treating physician about pregnancy? What did he/she say?
We can certainly provide you information BUT you should be monitored by your physician due to your back and pain issues prior to trying to get pregnant. I hope this information helps. Please keep us updated.
