Fibromyalgia(FMS) andchronic fatigue syndrome(ME/CFS) both can be exacerbated by physical trauma.
It’s common for people with these conditions to be especially concerned when facing surgery.
The specific issues we could face after surgery are numerous.

Post-Operative Pain
Both FMS and ME/CFS involvehyperalgesia, which is the amplification of pain.
That means we’re likely to suffer more post-surgical pain than most people, and therefore greater debilitation.
Especially in FMS, the mere presence of surgical pain could trigger a symptom flare.
Dehydration may lead to problems with vasovagal syncope (dizziness and fainting related to low blood pressure).
Some people feel that the muscle relaxant succinylcholine can lead to postoperative myalgia (muscle pain).
These issues could potentially complicate your recovery.
In the end, it’s you who has to live with those consequences.
