Muscle stiffness , joint pain and skin rash

Hi, I am a normal healthy 20 year old female. Three years ago, during my Junior year of High School, I had a very strange physical occurrence. Seemingly out of nowhere, my shoulders and elbows began to hurt. Then, my neck and jaw. Within an hour, the pain was almost unbearable and I have a very high tolerance for pain. The pain spread to my knees, ankles, hips, and even toes. In a matter of two hours, I went from feeling perfectly fine to every joint in my body being in tremendous pain. My body froze up, and I could barely move anything due to stiffness. It felt as if the muscles were tearing off my bones. This pain and stiffness went on for about a week, I was only able to deal with it by taking as many Advil as safely possible. After that first week, I spontaneously developed a full body rash, along with LARGE bumps on the tops of my feet, hands, and shins. I decided to see a doctor, who informed me something in my blood was much higher than normal. Unfortunately, it was three years ago and I don't remember what that was. He recommended I visit a Rheumetologist. These symptoms remained for three more weeks. At some points, it felt as if the symptoms were easing up, but sometimes they were so bad I could not even crawl along the floor. I was literally frozen in pain and stiffness. I tried Icey-Hot which made it feel like my muscles were on fire. Some nights I could barely sleep, I could not move my arms or legs, but the pain was so bad, I rolled around in torture. Massive doses of Advil and laying in a hot springs pool were my only minor means of relief. After about one month, my symptoms finally easy up and disappeared as quick as they had come. Just as my symptoms vanished, I made it in to see a Rheumetologist who informed me I was perfectly fine. After three years, I still wonder what that was. I find it strange because I have always been a healthy normal person and have barely ever had a cold. It also seems odd that this would happen to such a young person. I wonder if this could ever happen again. It is going to bother me until I find an answer to what this was.
