Never is death less painful not ever!!!!!! the ones left behind carry the pain,the guilt, the helplessness with them for the rest of their days.
if you are not insured one can go to the mayo clinic , the healthy department... Please do not end your life! meds will control the pain. I do not know of over the counter meds I am not a doc and a doc is the one you need to see. sometimes a warm or hot heating pad on the area helps warm the nerve and clam it down.
stay in touch and vent here if you need to we care and are a few typed words away. Stay strong and hold on till you can see a doc. sending low pain to you.
PEACE
