My body is failing me

Hello everyone. I hope you and your loved ones enjoyed your Thanksgiving holiday. I did as well waking up at 2 am and putting the meat (pork) in the oven. My job was kind of doubled. I was making one for my boyfriend's mother and making one for myself as well as a whole chicken. I do not really do Turkey I had so much of it as a child that it is really not the same for me anymore. Well, this is not the reason for this blog today. Today, well yesterday around 12 noon I started the potato salad and the rice with pigeon peas, also known as arroz con gandules. My fingers started to stiff on me, but I did not pay too much mind to it. It was time to take the potatoes out. I started to mix in the ingredients when my thumb and pointer started to give me trouble like they started to " lock-up" on me. I know sometimes Lupus can mimic the symptoms of arthritis but I have NEVER felt this before. I was scared and my teenage son, who was in the kitchen with me, saw this, he said nothing until I told him to help me with the potatoes. So I just thought I am no longer messing with the potatoes I should be able to peel the egg. I started to peel but it started locking-up on me again and I constantly had to stop and try to reposition my fingers, several times. I hurried with the eggs and tried to relax. It was still bothering me when everything is done and it was time to cut the meat and serve everybody. Then it was time for me to get dressed and go to my boyfriend's mother for thanksgiving. I changed my outfit and now it was time to put on my shoes. My toes on each side of my feet were in unison with my fingers. They locked on me several times throughout the evening. I dealt with the pain until the night's end.

Has this occurred to anyone before? I was scared, but I did not show it. Worried is an understatement. Please is my body breaking down? How can I stop it?
