I am pleased to hear that you are diving safely and confidently.
A Physiatrist (pronounced "Fizz - i - a - trist") is a physician who specializes in Rehabilitation Medicine. While Neurologists diagnose MS, a Physiatrist helps a person achieve his / her maximum potential despite a disability. We often specialize in the the care of people with MS / Spinal Cord Injury. We treat weakness, paralysis, sensory disturbances, spasticity, pain, bowel / bladder dysfunction, orthopedic complications and other problems.
Physiatrists who work with MS or other neurological conditions often partner with Neurologists to achieve the best comprehensive care possible.
There sometimes is confusion about what we do based on the spelling. A Physiatrist is a rehabilitation specialist. A Psychiatrist is, of course, someone who specializes in mental and emotional disorders. Two entirely different specialties!
I think there is a adaptive diving organization in Houston. Search the internet for their site. Their experience can be very helpful in making diving with a disability a safe and comfortable experience.
Yes I am a Physiatrist. I also have a spinal cord injury and have been a wheelchair user for years.
Happy and Safe diving!
PS
Yes, summer in San Antonio can be hot, but the lower humidity makes the heat index lower than Houston. It is also great place to live.
