Short answer is ask for a referral to a specialist.
Long answer is that collateral ligament injuries take 6-12 months to settle and if you are over 40 will ache intermittently for the rest of your life.
Sponge balls are stupid. They limit your movement to no more than the size of the sponge ball which means you never get full range. Better to push it down with the other hand as far as possible and then hold for 10-20 secs. If the joint seriously wobbles when you try to move it side to side go back to GP and ask for immediate referral
Thanks Chris. I'm 50. There is no wobble in the joint, finger is pretty much straight if I do a 'flat hand' - joint itself feel 'secure'. If I feel around the slightly enlarged joint with thumb and index finger of other hand, I can't detect anything 'untoward', only tenderness if I squeeze joint hard (apart from ache described). Once 'settled', could an intermitment ache mean as high a frequency as every day, or just occasionally if finger pushed beyond new restricted limits. I've just tried to press fingers into my palm, and the injured finger physically doesn't feel like it can be pressed into contact with palm, but I'll start this exercise and keep going.
Given I visited the GP just a few days a go, is it worth trying the exercises for 2-3 weeks/longer then going back, or is there a 'time of the essence' factor. I'm wondering what the likely options might be likely should I get to outpatients (perhaps with my finger in much the same condition as now). I'm guessing that that there's a chance high res xray/ultrasound(?) might not actually reveal anything if soft tissue damage only?
Hi FF, I didn't know you'd come off. In Abingdon? Sounds similar to me fingerwise.
