Idk but I was trying to find this thread because I realized something. I have a scientific/ analytical mind, and whether it's about ptsd or not, for a little while now I ask myself, "What is possible, but what is probable?" Only you know your lifestyle, state of mind, whether it's affected by body position, nicotine or alcohol, etc. Not meaning at all in judgment, but rather to find the answer.
I was thinking of this with drs: my dad had been a drinker, (good) dr assumed cirrhosis. My mom said, he's been sober 14 years, are you sure? Dr raced off and came back eventually with a primary cancer location. My aunt started to act like stroke symptoms, they said COPD. We said, she has been around 2nd hand smoke, but never smoked in her life, are you sure? We demanded more tests and they came back with treatable bacterial pneumonia (1 gallon of fluid in the lung). Same aunt had one of several joint replacement surgeries, they said she's afraid to walk more than 3o feet. We said impossible. Took a week of demanding (since based on pain reports we said she'd never give), and sure enough one of the other artificial joints was completely dislocated. My mom was diagnose with arthritis, vey good dr knew she had quit smoking 3 years before, and checked for lung cancer. A person had trouble with her eyes, feared early onset/ medical emergency glaucoma (genetic history), but they were inebriated. (It passed with sobriety). And things not even discovered yet.
An odd example, when my or others hair goes dry as straw out of the blue- I see they or I will test positive for Covid in a few days, though no symptoms other than maybe exhaustion or short in patience will be present then. But all the hair conditioner in the world wouldn't help.
My point is, (just saying for me, ptsd included), I say now to myself, x. y or z occurs, could it mean or should I fear l, m,, n, o, p? And I say, knowing facts is it possible? Yes. Probable- maybe not at all. Whether it's physical (including genetics, they can be overweighted to the moment), ptsd, trust, perspective, or cognitive distortions. (Just saying for me only).
Be careful, and be curious, and hope you can get resolve. Just disregard this if not helpful. You know you, your body, your norms, your habits, your mindset, your thoughts, perspective and stressors better than anyone else. Welcome to you.
