Dr. Charl Ceronio, M.D.'s Expert Contributions
Should I go to the doctor?
Id say going to a doctor is a good idea, and Ill tell you why. This might be a simple case of cerumen impaction in your ear and lymphadenopathy under the chin, but in eleven years, Ive seen things that turned out to be much more complicated. I dont want to frighten you, but I also dont want to minimize your concerns. Get checked out to be sure. READ MORE
What imaging tests might be appropriate for me?
Depending on your age and risk factors, your cardiologist might want to obtain a calcium cardiac score, a stress test, or a heart catheterization. Basically, a special CT scan, an EKG under exertion, or a contrast xray to show blood flow through the arteries around your heart. READ MORE
What is hypertrophic cardiomyopathy, and what are the management options?
Hypertrophy basically means growth, and in this case it means the heart muscle. When it comes to the heart, it can become a problem when the heart is so thick that the normal amount of blood cant enter the ventricles, which reduces the cardiac output of blood. There are medicines that reduces what we call cardiac remodeling, but youll need to stay on top of your blood pressure and be compliant with your BP meds to prevent heart failure. READ MORE
Should I be more concerned about my wife's injury?
Honestly, it sounds like she could have bumped her head more than slightly. The symptoms youre describing are consistent with a concussion. If she doesnt have an actual head injury, then she could very well have a virus on top of that. Did the symptoms persist more than a day? READ MORE
Phenergan
Phenergan or promethazine is an antihistamine in the same class as Benadryl. It is used to treat allergies and nausea, but can cross the bloodbrain barrier to help with sleep. You can take it, but some folks have a reaction that keeps them awake. If you cant take Benadryl, dont take Phenergan. READ MORE
Can someone live off of Ensure Clear Nutrition?
It does provide Calories and protein, but Im not sure if it has all the essential vitamins and nutrients. What is the nature of their eating disorder? If they are older and have a feeding tube, we can consult a dietitian and formulate a liquid that can provide the amino acids, vitamins, minerals, and healthy fats their body needs. READ MORE
What to do about a fever after flu shot?
Its normal to have a reaction to a vaccine its your immune system responding, but its rare to have such a strong response. If it continues for more than 24 hours or if symptoms worsen, please contact your primary care physician. READ MORE
Can medications help with arrhythmia?
Yes, there are different types of arrhythmias, but beta blockers and certain calcium channel blockers can help a great deal. Arrhythmias can be very dangerous, so please see your doctor soon! READ MORE
If I have a severe allergic reaction to food, what are the immediate emergency treatments given in the ER?
Most likely epinephrine if it's progressing to anaphylactic shock. You can also expect to get steroids and anti-histamines. READ MORE
What is the treatment for non-alcoholic fatty liver disease?
The best thing to do would be to speak to a doctor and/or dietitian about dietary changes. Fatty liver is typically caused by diet, and we here in America consume an excessive amount or processed food high in fructose, which directly causes fatty liver. READ MORE
Regarding blood under skin?
Are you taking an SSRI for depression or anxiety? Medications like Zoloft, Prozac, Paxil, etc. tend to cause easy bruising. Another possibility is something called "senile purpura," which is just easy bruising caused by aging. As we get older, we have less collagen in our skin, which normally keeps skin soft and protects small blood vessels. READ MORE
