DEAR DR. GOTT: I am disabled with extensive nerve damage from liver failure. I have a lot of problems. Just in the past few months, I’ve had spells where I yawn constantly. The problem usually starts shortly after I wake up, but it also happens later in the day. They aren’t wimpy little yawns, either, but those that start in your toes and gather momentum as they head north. By the time they reach my head, my mouth is wide open and I’m stretching my jaw as far as I can. This may go on for hours and simply wears me out, not to mention that it kinda hurts. Any ideas?

DEAR READER: Unless performed intentionally, yawning is an involuntary action involving many body parts. The mouth opens, the jaw drops, abdominal muscles flex, lungs expand, the diaphragm is pushed down, heart rate increases, and muscles and joints flex. The process is reversed as we force that air back out of the mouth. People of every age — even an 11-week-old fetus will yawn. And when we see someone do just that, we will likely follow along. To even read about the topic in my column will likely cause a person to yawn.Excessive yawning can be caused by a vasovagal reaction on the blood vessels and could indicate a cardiac problem, sleep apnea or excessive daytime fatigue. Because of this, you should address the subject with your doctor or cardiologist. Yawning doesn’t reflect boredom, as proven by athletes who will yawn prior to running a race or entering a swim meet. Therefore, I recommend you make that appointment so you can get to the bottom of the problem.To provide related information, I am sending you a copy of my Health Report “Sleep Wake Disorders.” Other readers who would like a copy should send a self-addressed stamped No. 10 envelope and a $2 check or money order payable to Newsletter and mailed to Newsletter, P.O.

DEAR READER: The localized form of scleroderma affects only the skin, while systemic scleroderma damages the heart, lungs, kidneys and digestive system. Symptoms and treatment vary, depending on the type.Localized scleroderma can resolve on its own, systemic cannot, but a variety of medications is available to reduce the intensity of pain and help control symptoms. Some drugs can dilate blood vessels, possibly reducing the severity of symptoms of conditions such as Raynaud’s disease and kidney and lung abnormalities. Physical therapists can help a patient work toward methods to manage pain, improve mobility, and increase strength. The appearance of skin lesions can be helped through ultraviolet-light exposure or laser surgery.On the home front, a person should remain active, protect the skin from cold, discontinue smoking, and refrain from eating foods that contribute to heartburn or gas. Walking, yoga or tai chi might be to your liking. Should Raynaud’s be present, remember to protect your hands at all times, such as by wearing gloves when placing foods in or taking them out of the freezer, or when hanging clothes on the line to dry.————————DEAR DR. GOTT: I have read about plantar warts that your readers have. Well, I have seed warts almost over my complete back, and they have spread to other parts of my body. My grandfather also had them on his back. My back itches badly all the time. Are they inherited? Is there anything that will help me get rid of them? I have shown them to my dermatologist, and he said he could freeze them off but that was about all he could do. What do you think?

DEAR READER: Seed warts are simply common warts with black dots that originate from the blood vessels that surround them. They commonly appear on the face, fingers, soles of the feet and backs of the hands. They are contagious and caused by the human papillomavirus (HPV) that enters the skin through a simple cut or crack. Latent infection can also occur in people who harbor HPV without skin trauma.As with all warts, a number of treatment methods are available. However, because there is no single cure, some may appear ineffective. One option is cryotherapy. Liquid nitrogen is applied to freeze the wart and can be painful but effective. In my opinion, this is your best bet with the process performed by a dermatologist; however, liquid nitrogen can be purchased at your local pharmacy without the necessity of a prescription. The nitrogen freezes and bursts skin cells that contain the HPV, thus giving the immune system an opportunity to attack and destroy the virus. Then there’s minor surgery or laser surgery. The disadvantage to surgery is the expense and the warts might scar the skin.———————-
