I've been wondering whether I have RSD. I hope the experts here can help me identify.

About 8 months ago, I had a problematic blood draw on my right arm. To make a long story short, the phlebotomist put a bandaid on the puncture site, while the proper procedure calls for something that causes pressure.

I developed a big hematoma because of this none-pressure bandaid. (Hematoma, according to my online research, can damage nerve.) I started to have pain when I bend the right arm backwards or pull it down when it's holding onto something. Fortunately, these movements are infrequent in my daily life, so I waited patiently for the healing of the nerve.

In the meantime, I noticed my right hand sometimes becomes stiff in the morning, a symptom that's very common today.

For about 5 months, these pain didn't get better or worse, until I tried out folk dancing, which involved some arm-pulling movements. It were moments of pain while I danced, but seemed temporary. After the 4th time I danced, I noticed new pain that haven't gone away: elbow pain when I flex the forearm, or when I extend my right arm to grab things. When I pressed different spots of forearm and arm, there were pain too. Throughout the day I would have many cries of pain. All these pain started about 6 weeks ago.

I thought the new pain was caused those arm-pulling movements, so I stopped folk dancing. About a week ago I went to a weekend of light dancing workshop. The only hand movements were clapping of hands, which don't cause pain and should be ok, according to my speculation back then. Still, after this workshop, I developed new pains: sometimes pain on the right neck, or sometimes constant pain on the right upper arm, or pain on the right shoulder. I now think it's because I over-exercised my right arm.

Besides these pain, during the last 6 weeks, I sometimes feel I have arthritis on my right arm. I don't sleep very well at night, because I have to avoid certain posture that causes pain.

So it seems, each time I exercise my arm for a few hours, my pain become more wide-spread. I don't have any sensitivity issues, nor do I notice any skin changes.

Do you think I have RSD? I also wonder whether RSD is a curable illness.

Thank you very much for your help.
