How do you manage the pain of bone cysts?

Around Christmas 2010 i started getting pain in my right wrist (i am right handed). I didn’t know what was wrong and presumed it was a sprain. I work in a nursing home in the holidays and a couples days previous of the pain in my wrist i strained it from stopping a resident from falling over. At the time my back hurt and i didn’t think anything off it but the pain wouldn’t go so i saw the doctor and he said that i had sprained it and all i could do was rest it and buy a tubby grip so i did. It eventually stopped hurting as much. Every now and then i would get a tinge of pain but it was manageable. Then half way through university term it randomly started hurting. So much that i could do anything with it! It was even a struggle to do the button on my jeans up. I booked an emergency doctor’s appointment with the university doctors and he was a baffled as i was so booked me into have an x-ray. Since then i have had the result back which showed i had never sprained my wrist but i have a cyst of the lunar bone which is a little bone on the wrist. My doctor says there’s no treatment for it. I am now back working in the nursing home and my wrist is aching like crazy and really hurts. I don’t really know what to do. Anyone have any knowledge or experience of this? And know what i should be doing? Suggestions would be much appreciated! Thanks
