I would like to know if somebody's hands are shaky, not because tht person is old, hyperactive or afraid, can there be any other factors causing it?
Perharps having nervous system problems?
You have several posts in the forum; I'd like to take the opportunity to answer all of them here. (Others might reply to your posts individually, so don't ignore checking back there.)
First of all, shaking in a younger person can range from simply too much caffeine to not enough B-vitamins to hyperthyroidism to, as you mention, nervous system disease. Chronic alcoholism can do it too. Is the shaking at rest or only when the person uses their hands? A family doctor could tell at a glance what type of testing (if any) is necessary; in-person examination is required for an answer on this one.
You've asked previously about laser eye surgery. I don't have statistics at my fingertips, but the procedure seems to be well tolerated and overall, successful. There are reports of intractable pain and worsening of vision however, so like anything else, risks vs. benefit have to be weighed individually. My personal (NOT professional, as I am not an eye expert) feeling is that since we don't have a lot of data on how the eye ages after such a procedure, I would be hesitant to do it to both eyes. I.e., if the procedure turns out to fail in older age, I'd want at least one eye to still be intact and correctable with lenses. Admittedly, this point of view is a bit irrational, as who wants only one eye corrected??
Regarding a tight bra and breathing: does loosening the bra correct the shortness of breath? You also mention that your rib cage sticks out on the left -- this is usually due to scoliosis or perhaps a rib cage deformity such as pectus excavatum (pigeon chest, funnel chest, etc.) THIS could cause breathing problems and/or chest pain. Besides getting the usual work-up for shortness of breath by the family doctor, a chest x-ray should be passed on to an orthopedist if it indicates any of these deformities.
The itching and other symptoms you describe after drinking beer sound like a potentially serious allergic reaction which should be verified by an allergist. (Strange that your friends should have similar reactions as I am not aware that beer allergy is so common -- who's putting what in your beer folks??)
Finally, pimples on the back of the body are most likely due to hygiene issues, as sweat in that area is sometimes not readily rinsed away if you take fast showers. If quite the opposite occurs, i.e., you vigorously scrub your back with a back brush or loofa, etc., you may be irritating the pores and stripping the skin of its natural oils, leaving it more prone to injury and pimples. Not-too-hot water, pH-appropriate, mild soaps, gentle washing and perhaps a dry brush massage here and there should be enough to clean the skin of soil, while stimulating circulation and encouraging the sloughing off of dead skin cells (which would otherwise clog the pores.) If these basics don't help, or if the skin is obviously infected with deep cysts, etc., consult a dermatologist.
'Hope that covers everything.
Best of health, Dr.B
