Post-COVID Symptoms: Taste Changes and Skin Concerns Explained

Please inquire about issues related to diagnosis?

Hello Doctor, I was diagnosed with COVID-19 a while ago.
This morning, I felt post-nasal drip, so I took a mucolytic medication prescribed by the hospital.
I haven't taken it in a long time, and it seems a bit sour to me; occasionally, I also notice a slight bitter taste.
Is this normal? I'm a bit worried about a possible taste disorder, but I haven't experienced any issues with other foods.

Additionally, I've noticed a small blister-like bump on my left middle finger, and I'm unsure if it's from a burn or if it could be a lingering effect.
If it is just a burn, should I leave it alone, or is it better to puncture it with a needle? Thank you for your explanation.

Hello, the taste of phlegm is indeed slightly sour and bitter, which is normal.
Regarding the small blisters, it is likely that they were caused by accidental friction.
There is no need to puncture them with a needle; they can be left to absorb on their own.
Thank you for your question.

Post-COVID symptoms can manifest in various ways, affecting different systems in the body. Your concerns about taste changes and skin issues are valid and not uncommon among individuals recovering from COVID-19.

Firstly, regarding your taste changes, it is not unusual for individuals who have had COVID-19 to experience alterations in their sense of taste. This can include sensations of bitterness or sourness that were not present before the infection. The virus can affect the olfactory and gustatory systems, leading to temporary or prolonged changes in taste perception. While many people regain their normal sense of taste within weeks, some may experience lingering effects for months. If you are noticing a consistent change in taste, it is advisable to monitor it closely. If the issue persists or worsens, consulting with an ear, nose, and throat (ENT) specialist or a healthcare provider may be beneficial.

As for the small blister-like lesion on your left middle finger, it is essential to assess its characteristics. If it resembles a blister, it could be due to several reasons, including friction, heat, or even a mild burn. If you suspect it is a burn, it is generally advisable to keep the area clean and protected. You should avoid puncturing the blister unless it is large and painful, as this can increase the risk of infection. If the blister is not causing significant discomfort and appears to be healing, you may not need to take further action. However, if it becomes red, swollen, or shows signs of infection (such as pus), you should seek medical attention.

In the context of post-COVID symptoms, skin manifestations can also occur. Some individuals report rashes, hives, or other skin changes following their COVID-19 infection. These can be attributed to the immune response triggered by the virus. If you notice any unusual skin changes or if the blister does not improve, it would be prudent to consult a dermatologist or your primary care physician for further evaluation.

In summary, both taste changes and skin concerns can be part of the post-COVID syndrome. While many symptoms resolve over time, it is crucial to stay vigilant and seek medical advice if you experience persistent or worsening symptoms. Maintaining open communication with your healthcare provider will help ensure that any potential complications are addressed promptly. Remember to take care of your overall health, stay hydrated, and follow any recommended guidelines for recovery.
