Positives

• A long-hauler with moderate-severe ME/CFS, POTS, and histamine intolerance used a Micro-pulse P9 device for 2–3 weeks and experienced profound relief: able to take public transit, work 4–6 hours, and walk through a museum without crashing Reddit.
  
  
• A patient with daily headaches, migraines, and anxiety from Long COVID rented a Bemer PEMF mat for a month and saw roughly 80% improvement in main symptoms Reddit.
  
  

Negatives

• A CFS patient tried a PEMF device daily for several weeks with zero improvement, then developed constant nosebleeds due to PEMF’s blood-thinning properties and had to stop Reddit.
  
  
• A long-hauler who initially saw 6 months of improvement from a PEMF mat did a high-intensity session, passed out for 30 minutes, and reports severe cognitive decline afterward including seizure-like episodes Reddit.
  
  

Hurdles & Side Effects

• The Bemer device costs upwards of $6,000 in the US, and the patient who benefited could only try it because a family friend let them rent one at minimal cost Reddit.
