has a new drug been made for this problem that will reduce some of the problems of fibromyalgia
Hi Saeed, and welcome!
That's a very specific question, seeing as it's hard to get any new drugs to work at all.
So: No.
New meds are being developed and trialled all the time, but none as yet changing anything.
Best place to look for that kind of research is healthrising. Articles like "Looking Forward to 2022 Pt. II: Fibromyalgia and ME/CFS Clinical Trials Plus Six Potential Game-changers."
Or the studies, like on pubmed. The quickest overview is the yearly Italian summary of the most important studies, for 2022 it's "Fibromyalgia: one year in review 2023". Nothing about any new drugs there, only meta-reviews finding duloxetine, pregabalin "least bad", then amitriptyline. And one confirming that vitamin D supplements do on average really help.
Apart from that, that summary reports ozone, yoga & tai chi, "a modified high-antioxidant diet, weight control, and nutritional supplementation" can help, whilst Khorasan wheat improves FM symptoms via improving the gut biome. Various types of neurostimulation (TMS and tDCS) have promising results, but need to be tested further.
I've been analyzing my stiffness lately, and have detected a stiffness that comes from the tendon insertion points around the joints and a muscle stiffness. Both can come from holding postures, so keeping on the move helps me, as well as twist-stretching, for instance before I get up. But I've also found various cheats how to move quicker before the stiffness wears off without hurting myself.
I've also found out that both forms can be there or not independently of the severe Ache.
I use several supps (like the amino acid GABA) that relax muscles, e.g. my bladder pain, and they improved my stiffness.
Stiffness may be my most visible symptom, but it's not my most disabling, exhaustion is.
