Are you being seen by a Long COVID clinic? If not, I strongly suggest you try to get into one. I have had Long COVID for 3 years. It took a long time to be diagnosed and it is very disheartening to have repeated tests that show nothing wrong. I have pain, brain fog, issues sleeping, insane anxiety, dizziness, blacking out, GI issues, and on and on. Since being seen by the Long COVID clinic, I have Doctors and therapists who know what I have which is very comforting after years of being tested for everything and feeling like I was losing my mind. With Long COVID, you do not want to push too much in the way of exercising. My physical therapist started with breathing exercises to help me calm down. The first step being to calm down and remain calm which will give you more energy. I have had to try to cut as many stressors in my life as I can. The higher my anxiety, the worse my symptoms. I am 52 and can not do more than 20 minutes of minimal physical activity at a time. I have ended up in the ER due to overdoing it. I am on gabapentin for neuropathy that was not diagnosed until I was with the Long COVID clinic, it did require a skin biopsy. The gabapentin does help with pain. In addition, I was diagnosed with fibromyalgia and take Cymbalta. Cymbalta can help with mood, GI issues and nerve pain. I take Low Dose Naltrexone to help me sleep. Even if I only sleep for 3 or 4 hours at a time but get deep sleep during that time, it helps. The low dose Naltrexone has helped me with this. I have POTS - so I wear an abdominal binder so I can sit and stand. Is your wife experiencing dizziness? I have horrible GERD/Acid Reflux for which I take Dexilant. Prior to long COVID I ate well and exercised and only took zyrtec for allergies. I have a life sentence as all of my diagnosis are not curable, but I now have a better attitude and hope for reduced symptoms which helps a lot. I wish you good luck and will continue to pray for everyone with this awful condition.
