question: I played tennis today. I haven t played in 10+ years. Right wrist popped and had immediate pain, not enough to stop playing. Now 10 hours later, there is a knot on the little finger top side of my wrist, swelling, some redness and when having to turn hand upside down for any motion, lose ability to grasp or exert motion without much pain. Worried that it s more than a sprain due the small knot which popped up.
