I've been trying to work out why I have a clicking noise in my thumb lately. It's pain-free but every now and then the phlange joint in my thumb just does a click as if it was caught on something and then its freed itself. It's annoying rather than anything else.
I realised this morning that the Home Button on my smartphone is not working properly for last 4-5 months and sometimes i have to press it 5 or 6 times with my thumb to get a reaction. Could this be the source of my thumb issues - repetitive injury strain from Smartphone use!!!! You read how gamers can get RIS from overuse.
Anyone suffer from something like this or dx-ed their problems from overuse of a device or keyboard?
