Hello, my daughter is 35 and pregnant around 7 to eight weeks along, Shes been well so far. Yesterday though, she went to ER after she had eaten a salad for dinner at work, a lump formed below her chin area. She told me the Dr noticed it right away ,did a thyroid check it came back ok, was sent home as having an allergy to something she ate, and to take Benadryl follow up with family Dr. Today she did that he told her due to her pregnancy that's most likely what's causing her problem in her lymph nodes,told her to keep taking Benadryl and see her GYN if its not gone in a week, dose this sound accurate to you I mean about the lymph nodes? She told me this evening that she's really tired .I told her Benadryl will do that along with her working 8hrs .?Will pregnancy cause hormonal changes, or could she have an infection? ER did take blood test would tat have showed infection? We'll I'm I am just curious the swelling is from being Pregnant like her family Dr said? Thanks rom concerned mom
