I hurt my finger in approximately late June early July. I bent it backwards really hard. It was bruised and swollen for about a week. Now I only experience dull aching and sometimes sharp radiant pain throughout the length of my thumb when the weather begins to change and when I injiury it in a minor way say as bump it or smack it against something. I don t know what I did to it and I don t undestand why it is still hurting.
