@edgarblythe,
As I mentioned to you elsewhere online, it's very pleasing to read that you might have an inexpensive solution to your hearing loss.
As for the VA hospital, I may have spoken to you about this before so forgive me for possible repetition. Over the span of time of the last 5 years, many VA hospital, medical care facilities have greatly improved their medical care. Rules , procedure and retraining has swept out a lot of the bad and poor care in many facilities.
While I can't tell you what might be true for Houston area veterans, I do know in FL and in Albany NY the care is very good to excellent.- spotty to below-avg in Manhattan. Both my cardiac (replacement of pacemaker /defib) and oncology issues (Non-H Lymphoma diagnosis and treatment and now in remission) . I do know that qualified veterans do got low or reduced cost eyeglasses and hearing aids when diagnosed with hearing loss.
While that doesn't mean the same is true for Houston area, it might mean you could be passing up some decent medical care that might cost you very little.
VA medical care system, on the whole, has improved the veteran's wait time after registering initially and receiving the care requested. It used to take months, now is down to a relatively short time or there's hell to pay. My processing initially took 1-2 weeks. Got good non-emergent care by GP, within 3 weeks.
I might advise you to give them another chance if it's been more than 5 years since your last visit to VA. Just a thought.
