Should I tell my ear, nose, and throat specialist about a hard, painless, pea-sized bump on the back right side of my head that has not grown in two weeks, especially since I am currently taking Hetrazan for a high white blood cell count?
Yes, you should definitely mention this bump to your ear, nose, and throat specialist. Since you are currently taking Hetrazan (diethylcarbamazine) for an elevated white blood cell count, this bump could be a swollen lymph node reacting to the same underlying issue your medication is treating. It is very reassuring that the bump is small and has not grown, but your specialist will want to examine it to ensure everything is healing well. Please don't worry, as these bumps are very common and often harmless, but sharing this with your doctor helps them provide the best care for you.
