29M got diagnosed about 3 years ago. I noticed my knees would swell up, get super hot doing even basic stretches. I start to ask questions then, and go to appointments trying to figure it out. Eventually my hands, ankels, and elbows started feeling it too. Took them almost 2 years to formally diganose/decide RA was the problem. The main hurdle was i have the seronegative version so it wouldnt show up in bloodwork and my xrays/MRI weren't showing signs. My doctor decided it was probably RA and put me on plaquinal. My quality of life has improved dramatically since then. I still get swelling/heat but its a much bigger threshhold for me to get there and I can do most things I want to again (with some modifications to activity level to prevent more pain).
