Allergy / Dizziness / Lower back pain / Difficulty urinating

Hello Doctor, I received the AZ vaccine at the beginning of August, and I did not experience significant side effects during the process.
However, in mid-September, I developed an allergic reaction on my palms and the tops of my feet, resembling hives.
After the doctor prescribed medication, it improved and did not recur, but I am unsure if this was a side effect of the medication or an adverse reaction.

Starting in early October, I suddenly experienced lower back pain, along with frequent urination (even though I haven't consumed much water).
Additionally, I have a sensation of urgency without being able to urinate, and I often feel dizzy and have dry mouth throughout the day.
I also experience blurred vision at close distances.

I would like to know if these symptoms could be related to the vaccine, as I did not have any of these issues prior to vaccination.
If I need to get checked, which department should I visit at a general clinic, or would it be faster to go directly to a hospital? If so, which department should I register for? Thank you.

Hello: Based on the symptoms you described, since your discomfort occurred at least 4-5 weeks after the vaccination, it is less likely to be a side effect of the COVID-19 vaccine.
The symptoms that began in October are more likely related to a urinary tract infection, so it is recommended that you consult a nephrologist or urologist for examination and treatment.
Additionally, your symptoms of dizziness, dry mouth, and blurred vision may be complications associated with the urinary tract infection.
It is advisable to complete the treatment for the urinary tract infection first, and if these symptoms persist afterward, you should seek further medical attention.
Given your described condition, it would be recommended to visit a hospital, as the specialists available there can provide more comprehensive care.
Thank you for your inquiry.

Hello! Thank you for your detailed inquiry regarding your post-vaccination symptoms after receiving the AZ vaccine. It's important to understand that while vaccines, including the AZ vaccine, can cause a range of side effects, most of these are mild and temporary. However, your symptoms seem to be more complex, and I will address them in detail.

Firstly, the allergic reaction you experienced, resembling hives (urticaria), could indeed be a response to the vaccine, although it is also possible that it was a reaction to the medication prescribed by your doctor. Allergic reactions can manifest in various ways, including skin rashes, itching, and swelling. If the symptoms improved with medication, it suggests that the treatment was effective, but it does not definitively indicate whether the original cause was the vaccine or the medication itself.

The sudden onset of lower back pain and frequent urination, along with the sensation of incomplete urination, could be indicative of several underlying issues. One possibility is that these symptoms may be related to dehydration, which can occur if you are not drinking enough fluids, especially if you are experiencing dry mouth and dizziness. Dehydration can lead to kidney issues, which might explain the back pain and urinary symptoms.
Dizziness and blurred vision can also be concerning. These symptoms could be related to a variety of factors, including dehydration, anxiety, or even a potential vestibular issue. It’s essential to consider whether you have been under stress or if there have been any changes in your lifestyle that could contribute to these feelings.
Given the complexity of your symptoms, it would be advisable to consult a healthcare professional. If you are considering which specialty to visit, I recommend starting with a primary care physician or a general practitioner. They can perform an initial assessment and determine if you need to be referred to a specialist, such as a neurologist for dizziness and vision issues, or a urologist for urinary symptoms.
In terms of diagnostic tests, your doctor may suggest blood tests to check for dehydration, kidney function, and any potential infections. They may also recommend imaging studies if they suspect any structural issues related to your back pain.
It’s also worth noting that while vaccines can cause a range of side effects, severe or prolonged symptoms are less common. If your symptoms persist or worsen, it’s crucial to seek medical attention promptly.
In summary, while some of your symptoms may be related to the vaccine, others could be due to different underlying health issues. A thorough evaluation by a healthcare provider will help clarify the situation and guide you toward appropriate treatment. Please take care of yourself, and don’t hesitate to reach out for medical help if you feel it’s necessary.
