Hello, Thanks for writing to us If swelling and tenderness persist, there might be possibility of delayed union or non-union. The cause may be soft tissue interposition or malalignment. (which means soft tissue is getting in the way of the bones joining) So I suggest you getting this evaluated by your doctor. You may get a repeat x-ray to see fracture union. Meanwhile, you can take Tablet Motrin 1 tablet with food as and when required (upto 4 tablets daily) to reduce pain. Hot saline fomentation over thumb will help decrease joint stiffness. Hope this helps you. Let me know if you have any more concern. Wishing you good health... Regards.
