Hi just saw your thread. I had botox injections a little over a month ago. I had a very bad reaction,excruciating pain in the first 2 weeks then I started feeling relief. The scalpular pain definately got better, then I had trigger pt injections in rhomboids,traps,levator and teres minor and all got better except I have pain in my Triceps,Traps and arm nerve pain still. i think it is already starting to wear off, so in my case about 30% releif for who knows how long? I think it was worth it for my level of pain beforehand but I dont think I would do it again.
