Are hyperbaric dives a possibility for relieving post-stroke issues?
Sorry to hear about your situation.
To start with, I have never heard of any proven benefit from hyperbaric dives for stroke treatment. As far as I am aware, they are only used - with limited evidence - for people who have radiation induced vascular disease. From your description, your husband does not have this. One alternative type of treatment you might consider is seeing an alternative medicine therapist or accupuncturist. Some of my patients have had success with this.
With regards to his electrical shock feelings, I have found that these can often be well controlled by the use of older-generation anti-depressants or with anti-seizure medications. Please ask your doctor if these would be appropriate in his case.
To help with your overall care situation, I would also recommend the following: 1) Consider talking with a social worker about getting help around the house, or even moving you and your husband into an assisted living facility. That may be covered by insurance and may make both your lives more manageable. 2) Consider having him seen by a Psychiatrist. It sounds like he has depression and is not living his life to the fullest - up at night watching TV is not a good way to recover from a stroke. A Psychiatrist may help with his depressive medicines to tailor them appropriately. 3) Consider having a conversation with his doctor about how to very strictly control his stroke risk factors - blood thinners, cholesterol, diabetes, hypertension - and how to do it more cheaply. Often, people don't realize that there are less expensive medicines that are equally effective for the treatment of their diseases.
Good luck!
