Patient Comments: Flu Vaccination - Side Effects

Did you have any side effects of your flu vaccination?

Comment from: flippy, 35-44 Male (Patient) Published: October 18

I have been getting the flu shot for the past few years. The warning always said not to get the shot if you have a fever etc., so I've always only taken it when I'm not sick. Generally after the flu shot, I feel weakness, headaches, a small fever, or chills. This year was no different. About 6 hours after the shot, I became very tired, and had minor chills, requiring a blanket. Fifteen hours after the shot, I had powerful chills, requiring a thick blanket and a heated pad. Eighteen hours after, I felt hot, no longer requiring any blankets and I still have a headache and feeling weak.

This is the first year I have ever had any reaction. I have been getting flu shots for years and have no doubt they have kept me from getting the flu. This year my arm was sore a few hours after the injection and is still sore 24 hours later. The soreness is in my shoulder, all the way down to my fingers. It is even in my under arm and moving into my breast. I did notice this year it felt like the nurse jabbed me extra hard and that the needle was much larger than ever before. Other years I could barely tell they were giving me the shot.

I had a flu vaccine a few weeks ago. I have been feeling lethargic and sluggish. I'm always a person on the move. This has knocked me off my feet. My joints ache all over. My back, shoulder, wrist and my whole body hurts, like never before. It hurts to sleep. I have never had pain like this before.

I have gotten flu shot every year and never had a problem until this year. Went to the local pharmacy for a shot and I don't think the pharmacist had ever given one before. The pain when he gave it was unbearable in my arm. Next morning I woke up with a severe headache and pain in my arm that radiated to the front of my chest. I was nauseous, dizzy and in pain all weekend. I had tingling in my hands and 3 days later have so much rib and arm pain on the side I received the shot in.

It has been less than 2 weeks since I had the flu vaccine. I have migraine like constant headaches, vomiting and problems with my vision. I can't look sideways as it is double vision or blurry. I can't walk far for the dizziness that strikes. My doctor said I was his 5th patient with these symptoms this week.

I got a flu shot in late November 2012, because I have an infant granddaughter and was urged to do so to protect her. Within a day or so, I developed a very itchy rash on my arm beginning just below the injection site. In the next month it spread down my arm. It took months to clear up. I still have marks on my arm almost a year later. There is no doubt in my mind that the rash was from the flu shot.

I received the flu vaccine yesterday at 1:00 pm. By 7:00 pm, I experienced chills, low-grade fever, pain in my neck and upper back, watery eyes, cough, runny nose, and joint aches. I am feeling better this morning, but still have pain at the injection site (which covers my entire upper arm muscle), runny nose, and general weakness.

I just got the flu on Sunday and I'm 26 years old. I got it last year without any bad reaction so I decided to get it again. About a day and a half later, and got a mild sore throat. The next day my sore throat got worse, I got a runny nose and then a stuffy nose. I had aches and pains, hot flashes, chills, and a bad headache. Two days later, add a cough and extreme tiredness to the list. Today, I'm feeling miserable. I have a cough, stuffy nose, I'm very achy, very tired, have the chills, and am irritable. I'm usually really healthy, but this shot hit me like a bomb. I may not REALLY be sick, but my poor body THINKS it's sick.
