anyone experienced hammer toe?

My husband had something similar and it got worse before we actually did something about it, so I'd say don't wait too long on this one. Hammer toe tends to get more uncomfortable over time, especially if he's wearing tight shoes regularly, so it might be good to bring him to see a foot specialist or even start at the polyclinic for a referral. I know KKH has orthopaedic services, but for foot stuff specifically you'd probably want someone who specialises in that, so a quick Google for foot clinics or podiatrists near you would help narrow it down. The earlier you get it checked, the more options you have before it needs anything more serious.
