Hi boyet and Happynapper and welcome to the Forum to both of you.
Folks often find that when their obstructive sleep apnea gets treated, many other health issues resolve. My RRT (Registered Respiratory Therpist) told it to me this way: Sleep is the kingpin in many of the disorders our bodies experience. Draw a circle and put whole sleep in the middle of the circle. Then, draw lines outward to each of the conditions you are dealing with. Each of the conditions that you are dealing with makes the other conditions worse, kind of like wind blowing on a marble that is in a circular rut. As each condition worsens, there is more wind applied to the marble and it goes around faster and faster...and you feel worse and worse. XPAP Treatment for obstructive sleep apnea has the ability to remove one or more conditions from your outer circle, which can then break up your cycle of ill health. On the other hand, if untreated obstructive sleep apnea is in the middle of your circle (as it very often is), then wind is being applied at every spoke of ill health in your wheel and your chances of recovery are practically nil.
It makes sense to go after the sleep apnea first...get it treated...to support your overall health.
The air pressure that is applied with CPAP treatment is really quite gentle compared with treatment on a ventilator. The CPAP machine does not breathe for you like a ventilator does. CPAP only applies gentle air pressure to keep your airway open so that you can breathe without obstruction and no longer have to struggle. I do not think that this air pressure causes throat pain. If you happen to be an obstructive sleep apnea patient who snores, the tissues in your throat were getting quite irritated every night in the nights before your CPAP treatment. The vibratory snoring causes inflammation and swelling...which then makes the vibratory snoring worse and the obstruction worse and your apnea worse. With my own severe OSA, by the time I got treatment, I had a rip-roarin' sore throat going on. It took a few months of CPAP treatment for this to get better. If my sore throat had persisted longer than two months on CPAP treatment, then I would have sought a doctors advice about it.
There is a definite connection between obstructive sleep apnea and GERD.
The dizzyness and ear congestion indicate something going on with your inner ear and this should always be investigated by an ENT (Ear, Nose and Throat specialist). Sometimes a sore throat will be present also, so...even though your dizzyness and ear congestion have subsided somewhat, it would be a good idea to have an ENT (hopefully one also specializing in sleep medicine) check this out for you. Please continue with your CPAP treatment as you are seeking care for your other conditions.
Our doctors do us a great favor by reminding us that we should not leave our OSA (even if mild) untreated. Untreated, mild OSA can have very serious health consequences over time. Good luck to you both and welcome again to the Forum.
