Over the last few days, I've developed a lot of pain in one arm - no idea what's causing it. It's so bad tonight, I feel tearful and irritable. Ibuprofen haven't touched it. Couldn't see dr tonight as DS2 had haircut and swimming, tomorrow after work DS1 has apt at Gt Ormond St so won't see GP till Wed at the earliest. Wondered if any of you have any thoughts. The worst pain is in the wrist, really tender and aches like hell. Also the elbow, and the shoulder - same thing, tender to touch and really, really aching. The whole arm aches from top to bottom. Haven't done anything unusual to have strained it - lots of dog walking but I tend to hold the lead in my other hand. There is a history of arthritis in my family and my mum has replacement hips and knees. Surely this isn't onset of arthritis at 45!! Nothing obviously swollen, just such an awful ache. Had flebitis once as a child but think that has other symptoms. Any thoughts of what might be causing this and pain relief. other than ibuprofen which hasn't had any effect? Long day at work tomorrow followed by London hospital visit, not filling me with joy...
