Microclots

Micro-clots or microclots are extremely small blood clots, and have been found in some Long COVID patients.

Long COVID
Micro-clots are a recognized symptom of Long COVID. They may result in reduced oxygen flow to large muscles; a hypothesis is that this reduced oxygen availability causes the post-exertional malaise or and/or exercise intolerance reported by some people with Long COVID.

Possible treatments
Rivaroxaban is an anti-clotting drug being investigated as a possible treatment for Long COVID patients with micro-clots.
