Is there a reason why i am having a problem with numbness?

Need more details: Can you provide more details? Which part of your body is numb? Is it just numb ( don't feel) or tingling (like falling asleep). How long you had the symtpms. Do you have pain in the same area.

Many possibilities: Numbness can occur from various reasons. Some potential causes include vitamin deficiency, nerve damage, nerve compression, alcohol over consumption, side effects of different medications, or as a result of different systemic medical conditions such as diabetes. Get evaluated by a professional to determine the diagnosis. Treatment is based on the diagnosis.
