Good day! I have my concern on my left index finger . I used to do my thesis for several months in my laptop and I was very busy typing my article. It happens that if I feel my hands were very oily I went to the kitchen and washed it again and again then the next day I just felt numbness on my left index finger and I could not write well. What would be the possible cause and at the same time what are the remedies because until now there is numbness. Thanks and Regards!
