Sciatic pain is the pain caused by irritation to the sciatic nerve which is really a bundle of nerves that originate in the low back and run all the way to the toes. So, sciatic pain can affect the entire leg. This nerve pain can be as annoying as an ache or be as searing as a hot poker (and everything in between).
Normally, the pain will improve in positions that ease tension on the nerve like the fetal position (knees tucked close to the chest). Strategically placed pillows are always helpful. A pillow between the knees helps to maintain alignment of the legs. And women should try a small towel at the small of the waist to help maintain the alignment of the torso when laying on the side. Personally, I love Zero Gravity chairs (see my recent post http://www.healthcentral.com/chronic-pain/c/23153/31764/solutions)
The prognosis is difficult to assess without looking at you and your MRI. But, I can say that time and patience are great healers. Keeping the swelling and inflammation under control in this early stage is very important. Research as shown that the chemical reaction of inflammation can cause long term damage to nerves and lead to chronic pain. Additionally, tricyclic anti-depressants (imipramine and desipramine) are very helpful in this situation because these medications reduce the nerve irritation and help you sleep.
Tylenol is harmful to the liver when taken in excess. Unfortunately, most of the opioid medications like codiene, morphine, hydrocodone, oxycodone are not that effective for nerve pain. One medication that is very useful for nerve pain is tramadol (Ultram). Talk to your doctor and discuss the options. With team work, you will feel better.
