RSI is a term that is used to cover a huge range of problems. It can include carpal tunnel, tendonitis and even dorsal wrist syndrome. RSI is normally caused when the muscle fibres change because this results in a decreased blood flow. Of course, nerve compression is also an issue but this is not always the first side effect that you may experience. This is because nerve damage often results from damaged tissue and inflammation. All of this is pushing down on the nerve which can result in the loss of mobility and even numbness, so as you can see, swelling is more likely to be the first symptom that you notice.
You will also find that the more pain you’re in, the more likely you are to have a reduced blood flow in the required area. You could go and see a doctor about this but at the end of the day, you would be better off going to see a hand specialist. You may also want to take some time away from whatever you are doing as well to see if you can recover but this is not always an option if you do it for a living. If you want to reduce the pain that you are experiencing then one thing that you can do is increase the circulation in your hands and your arms.
There are plenty of exercises that you can do to make this happen and if you are sedentary in what you do for a living or on a day to day basis then it can certainly help. Of course, other than going to see a specialist, the only other way for you to deal with this would be to have regular breaks from your repetitive motions so your hands can adjust back to normal again.
