Hi, Fibroproof! I hope you are feeling better by now. First of all, they are now thinking that you don't have to have all the tender points to have fibro. I know that I don't but I also take ibuprofen and Tylenol for pain so that could be why I don't jump off the table when they do the test. Also, my pain waxes and wanes so if I'm having a better day, the tender points don't hurt as much. Here is a link from the Mayo Clinic that explains this a little. It shows that you don't have to have all of these.

I get tingling in my fingers. Actually, when fibro hit me, it hit me around my joints...starting in my feet and working up my body. I thought I was coming down with rheumatoid arthritis because both sides of my body were affected. Then the fibro hit my elbows. I got that "electric-type" pain like when you bang your elbow and it shot down in my hands and stayed that way for two weeks! I couldn't do anything. When the pain settled down, it took months for my hands and arms to regain their strength. I even dropped a crock pot on my floor...dinner went everywhere.
Now, I don't have that problem very much. I will get tingling in my hands and I will get a sharp pain, like my muscle or tendons snapped like a rubber band. I just ignore it now. My fingers pop, too, when I open my hand from a closed position. We had Snap, Krackle, and Pop Club going a couple of years ago because of all the popping and cracking in our necks, etc. So, you are not alone.
It is unnerving when all of a sudden it seems like our bodies are falling apart. We don't know what is going on and neither do our doctors! We are so accustomed to thinking that our doctors know how to fix us up and heal us but that doesn't always happen. I have several chronic illnesses and I find that when I go to the doctor, they either don't know what is happening or they do know but can't do anything about it. So, I stopped running to the doctor for every little symptom and just accepted this illness. I've been much happier since.
You will become accustomed to what is going on in your body. You will see on this forum that you are not alone. You do need to make sure your doctor understands fibro and treats fibro patients. You want a doctor that stays up on all that is new with this illness. There are still doctors out there in the Dark Ages. My doctor is a board certified Internist that is also a diplomate. They have to take tests periodically to keep this distinction so they do have to be on top of new findings. Just like the link I posted from the Mayo Clinic, they are changing things all of the time.
So, try to relax. Take one day at a time. Don't start second-guessing yourself. Most likely, your rheumy knows far more about fibromyalgia than your primary care doctor. After all, these types of illnesses are their specialty. I know I would trust the rheumy if I were you. Plus, if you have read Fibro 101 and you see that you fit in this catagory, that should tell you that the rheumy is correct. Doctors do make mistakes. Remember, 50% of the doctors graduated in the lower half of their class and yours could be one of them. 
(This is a joke...not a commentary on your primary care physician.)
I'm glad the physical therapy is helping you. Don't let this incident set you back. You know your body better than anyone! Continue seeing your rheumy and just keep on keeping on, ask questions here, and get on with living a full and enjoyable life with fibro! Have a great evening!
