 [ Symptoms ] can cankor sores result in ear pain  i seem to have a cankor sore that only shows up on the right side of my tungue and my right ear always seems to be in pain at the same time this has occured at least three times [ Disease ] no it may be a sign that you have developed an allergy to peanuts you can have your medical provider order an allergy blood test for peanuts to confirm that this is the culprit in the meantime i would advise you not to eat peanuts and have some antihistamines like benadryl handy breaking out with hives after eating peanuts is not a sign of pregnancy sorry if you are having sex without contraception you can definitely get pregnant but there is no association with a possible peanut reaction
