Can help you with the next course of action and treatment plan. Would like to discuss in details and provide apt solution. Kindly consult.

Instead of having so many doubts at a later stage (after the CT is done), it is better to ask for dosing of radiation and the contrast medium, whatever you understand by it. Frankly, I am sure no doctor except the ones who are doing CT scan will have any idea about the dose of radiation or of the contrast medium. Moral of the story: Learn to trust your Doctor.

I understood your concern  and noted the problem as well .I need to ask few more details to make a diagnosis and start treatment and advice which suits you. Pl consult me on Practo , so that I can help you better.book a time slot as per your convenience for consultation.

In medical science,  it always weigh benefit against risk. If your symptoms and conditions is worth of multiple CT investigations , it should be done. Because , radiation due to multiple CT scan can harm or may not harm you.  It is uncertain and cannot be measured as radiation is only a risk factor. On the other hand, if repeated CT scan helps in diagnosis and follow up of serious condition,  it can be done.
