Postural Orthostatic Tachycardia Syndrome POTS (needs a differential diagnosis from Vasovagal Syncope – Differential Diagnosis of Vasovagal Syncope: Postural Orthostatic Tachycardia – PMC)
Pain – don’t write off the pain as all in your brain until you’ve explored other options – EDS can lead to pain. Someone who works with fascia or a gentle chiropractor (drop table, wedges, activator, avoid chiropractors who do pop & crack work) should be checked with if everything else has been ruled out.
Fatigue – POTS can cause massive fatigue & brain fog. EDS can contribute as well since muscles are compensating for tendons & ligaments.
Non-refreshing sleep can lead to the fatigue & brain fog as well.
Dizziness – POTS/Vasovagal Syncope
Sensitivity to heat/cold – POTS again, which can lead to Raynaud’s.
Sensitivity to lights & noise seems more like a high sensitivity thing, so related but maybe not as directly. Fragrances are definitely an issue with POTS. Some of my earliest episodes during puberty were triggered by chemical fumes. I was always sensitive to lights and noise, so only the fragrance part was new.
hypersensitive central nervous system that converts some normal sensations to pain (allodynia) and heightens the sensation of pain (hyperalgesia).
