Atom,
Hello and welcome to HealingWell. We are so glad to meet you !
I am sorry you are having pain, especially pain you can't pinpoint to a specific cause! I know it can be scary and frustrating. Because your symptoms are so broad it really could be a multitude of problems/issues. Some of these issues are not so hard to fix and others, maybe more serious or difficult. It's just hard to say with the symptoms you describe. It could be as simple to explain as your line of work, over-use of your wrists/hands, poor posture, or a muscles or nerve issue. My feeling is anything that continues or worsens over time needs to be checked out by a doctor, someone who can help you find a proper diagnosis so you can get the treatment that will help you. Otherwise you risk the problem worsening, etc.
If you can afford to please see your primary doctor for help figure this out. Hope you feel better soon.
Kindly,
Kitt
