I am sorry you are experiencing numbness and pain. Did you say the numbness only happens when you lay on a limb, or does it happen all of the time? Sometimes numbness can occur with Fibromyalgia. It's a common neurological symptom of Fibro. I have numbness in my left foot due to nerve dysfunction in my spine. My case is somewhat severe in that I have some other co-occurring conditions along with my Fibromyalgia.
As far as trying to alleviate symptoms- make sure you have a good mattress to sleep on at night and a good pillow. Don't sleep on more than one pillow and don't bunched it up. I purchased one of those a tempurpedic mattresses- It's wonderful! They also have tempurpedic pillows too!
As far as medication goes, and I am no doctor of course, but anti-seizure meds like Lyrica and Neurontin can be very effective for nerve tingling and pain for some people. I take a sister medication called Topamax, which works well for my nerve problems, but this one can also cause tingling too (ironic) when you are first getting used to it. I suggest talking to your doctor about your symptoms especially if it's been awhile since you've been in to see him or her. See what he or she suggests. Good Luck!
