Hello and hope you are doing well.
Your symptoms could be due to scabies. It is an infection caused by a mite Sarcoptesscabiei, it burrows in the skin folds of hands and feet and causes intense itching mostly at night. This is also contagious. You may need to consult your doctor who will examine you and may ask for blood tests and if needed may examine the scrapings from the skin to arrive at a diagnosis for appropriate therapy.
Hope this helped and do keep us posted.
stinging without redness or bumps could be nerothopathy, see your MD to get answers
