Dear ma m/sir, Hi! As far as thyroid is concerned before commenting as to what you should do I need to know the values, but if you say it is normal then you don t need to do anything. Low blood sugars specially after meals without treatment for diabetes is unusual and needs further investigation. For benign cystic thyroid nodule again you don t need to do anything except in case there is sudden increase in size or acute pain in the nodule you must see your doctor. Your first part mpv,p-lcr,pwd is not clear to me as to what are they. Regards!
