Hi, tatianne:
I was sorry to read of your anxiety over your soon-to-be-known MRI results, but I think your concern is fairly normal. Still, you simply can't let the unknown control your life. You'll know the results soon enough (a few days) and the result will probably not be anything scary, However, even if the tumor has grown a bit, you'll still have time and options. It isn't cancer. Try to keep things in perspective because allowing your emotions to keep you worried and fearful, possibly with no basis in fact, is not going to help you at all. I would suggest trying to keep busy, especially if you can help others while doing so.
The tingling, pain and numbness in your lower extremities could be caused by a variety of issues, including spinal disc problems. A spinal CT scan should help find or rule out such problems. My wife had similar problems and had numerous spinal CT scans (and an MRI) that showed nothing that might be causing her pain, numbness and tingling in her leg and foot. She had a consultation with a podiatrist that she wanted to remove a bunion and a heel spur that had been bothering her. A foot MRI scan showed the bunion and heel spur she knew she had, but also a neuroma between her toes as well as a small benign tumor in her heel. The tumor, neuroma, bunion and heel spur were surgically removed 2 months ago (3 hour operation, performed on my wife as an outpatient) and she is almost back to normal sans the tingling, pain and numbness. You just never know.
I pray you'll find peace and receive a MRI report that shows no growth. I also pray that the other issues will eventually be resolved. You have enough to deal with.
Jim
