Since hyperkeratosis involves various parts of the body differently, it is difficult, at times, to know who to see, so here are some suggestions for you. And the first is to visit your primary care physician, since he or she is the physician who knows you best and can ascertain the best line of treatment they think you should follow.
You will likely find them asking you about the exact nature of the problem and then they will look at it closely for themselves. From that, they can make recommendations as to who you should see.
For example, if you run into foot problems because of ill-fitting shoes that constantly rub your feet and cause corns and calluses, your doctor may simply recommend a shoe specialty shop dealing in specially fitted shoes. Often, because they are prescribed by your physician, you may be able to use your hospital insurance to help defray the cost.
Or, if your physician feels the problem involves more because he sees in the way you are standing or walking, you may find he may recommend a good podiatrist who can then give you a proper foot exam and recommend not only the right shoes, but, also, possibly, such items as shoe inserts that will help you walk correctly so that you eliminate the problem with your feet.
Further, your physician my look at the hyperkeratosis, if it is something like a lichens planus, and after looking at the lining of your mouth, he may recommend a good oral surgeon or oralofactory physician or specialist who has training in this. He may simply refer you to your dentist, as well, who will then make the recommendation. At the oral specialist, you will likely find the oral specialist will not only surgically remove the problem – a problem with which we are intimately familiar since we do suffer from this particular issue – and then send the results out for biopsy. Usually, this surgery is done in the office and takes about an hour and the specialist will use two types of sutures to close. The results will be back from the lab quickly so that a course of action can be followed if something serious is developing, while the healing process will take a week after which the surgeon will remove the primary sutures and the secondary ones will fall out themselves. You must also follow a rigorous dental hygiene program including regular rinses with salted water or with water and peroxide.
If your physician finds that you are developing actinic keratosis / hyperkeratosis, after a close examination, he may recommend a dermatological specialist who will also likely take a look at your problem with a special lamp and, if needed, the specialist may order a biopsy to determine whether the actinic keratosis is per-cancerous or not.
