Hi, Thanks for using HCM.
Fell down and then injured your fingers with ice covered on it. So the injury may be due to ice or mechanical injury. Since you have numbness
with one finger now with all others recovered, you will soon recover it also if there is no major nerve injury
. Keep doing your activities and use gloves for some time. Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take care.
