My mum has fibromyalgia and I’ve had pains in my knees only. I got them x-rayed, and both come back prefect. My question is, do all the trigger points happen at the same time, or, can they develop over a period of time? Could my knees be the first sign?

A doctor would expect someone with fibromyalgia to complain of pain in at least 11 of the 18 locations simultaneously, rather than at disparate times.

Your X-Ray would have been looking for signs of arthritis but it may be worth asking for a 'gait analysis', which any physio can asses should the doctor not be willing.

It will show up any rolling of the ankles which can cause knee pain.

Running shops are a good alternative. For around £30 (or often free if you buy a pair of trainers from them), they perform high-speed video assessment of your walking/running gait and you can see for yourself if it is responsible for the knee pain.

My wife's knee pain is 90% better as a result of doing this.

If the pain is persistent, do consider using some Atrogel^® twice a day and taking some Atrosan^® tablets additionally. The tablets take a few weeks to work but do help to reduce inflammation, which in itself is destructive to tissue if persistent.

Best wishes
