I'm ocular hypertensive, iop at base 16 (controlled). Does weightlifting increase eye pressure? What about normal breathing vs valsalva maneuver?
Yes but . .: Weightlifting, breath holding and being upside down will cause an increase in the pressure in the eye temporarily. So also will rubbing the eyes and any other activity which puts actual pressure on the eye. These effects are temporary and your having controlled glaucoma should not be an issue. Pressure has to be elevated for a long time to cause damage. ...Read more
Rare: In normal patients aviation does not lead to spontaneous pneumothorax. In people who have bullous disease or blebs (abnormal lung tissue that form large air sacs) pressure changes may lead to a higher risk of spontaneous pneumothorax. A person who already has had an episode of pneumothorax has as high as a 50% chance of having a recurrence without definitive treatment.. ...Read more
Not likely: Multiple sclerosis is a disorder affecting various areas of brain, spinal cord, and eyes, with differing events over time. An isolated gag reflex change is not suggestive of MS, and could well represent biological sensitivity variations. If this is a problem affecting eating or swallowing, might have your doctor evaluate. ...Read more
Slow foot reflex: Suggests possible nerve compression in lumbar or sacral spine, which could result from bulging/ruptured disc, bone spur compressing spinal cord or nerve root, or spinal stenosis. Suggest seeing orthopedic or neurosurgeon for evaluation, tests (including mri), options for treatment. If u have foot drop or similar problems, do not delay. Sooner the treatment, less damage. ...Read more
Is Chest expnasion of 5cm (currently 3cm while inhalation) while inhalation possible by deep breathing exercises using lung exerciser in 1-2 months?
Chest expansion: Hello ~ your question as written is difficult to understand but if I do, you are asking if your lungs vital capacity will improve with deep breathing and lung exerciser. Yes it will but to a max predetermined by your body size When the chest gets bigger for body builders that is muscle on the outside and not much increase in lung volumes. If that does not answer resubmit question thx ...Read more
Can increased icp from valsalva during weightlifting cause brain damage? Holding breath for 40 seconds at a time.
Generally no: HR has a reflexive response to BP and not ICP. The intracranial space is somewhat self-contained in that it consists of blood, CSF, and the brain. An expansion of one (as in increased ICP) is compensated by reduction in another. If compensation is insufficient, ICP rises and if chronic, leads to dec cerebral blood flow and may lead to herniation. You may see HR and BP changes during chronic phase. ...Read more
Yes. Which Style?: Yes. Obviously, any martial art or fighting that involves contact with the head can lead to concussion, traumatic brain injury, etc. There may be some styles which may be safer, such as Tai Chi & Aikido. These arts rarely have percussive impact. It all depends upon how you train. ...Read moreSee 1 more doctor answer
Is repeated startle response (i.e "jumping") harmful after I've had a concussion? My job involves sudden, loud sounds that often provoke startling.
May provoke symptoms: Although probably not harmful, loud noises and repetitive brain stimuli such as bright lights, heavy technology use, prolonged reading can all make concussion symptoms worse and prolong recovery. If you have to work, consider ear plugs or headphones if possible to reduce the loud noises and startling.

What are some physiological (non-psychological) causes of exaggerated spinal reflexes (i.E. Exaggerated jerking/flinching in response to light touch)?
Startle vs DTR's: Your description of exaggerated jerking with light touch sounds like someone with very brisk "startle" reflex, as in post traumatic stress disorder. This is a physiological response to hypervigilance, as ptsd encompasses the whole person and his/her body. Hyperactive deep tendon reflexes (dtr's) can result from conditions like cerebral palsy, strokes, inflammatory diseases, and brain injury. ...Read more
Several possibilitie: All these activities increase venous blood pressure during the action so it may be normal especially if you cough frequently. May also indicate inflammation throughout the sinuses particularly if there is nasal congestion or drainage. Make sure your blood pressure is normal. If body mass index over 40 may indicate benign intracranial hypertension. ...Read more
What causes trachea spasms (which blocks air passage) whenever coughing occurs? Is that an asthma symptom?
Age dependent: The trachea of younger kids is somewhat rubbery, like a soft silicone or thin walled plastic. It does not spasm, like the soft walls of the gut, but it can and does vibrate enough to produce some odd sounds ( the croup noise) common from ~6mo-6yr. In tracheo-malacia, ( a transient condition) the walls are much weaker and actually cave in on each other, but soft walls not spasm is the problem. ...Read moreSee 1 more doctor answer
