I’m diagnosed with psoriasis and recently with psoriatic arthritis as well and last few weeks I feel like I’ve been living in pure hell. I’m currently taking metronidazole and it does somewhat helps with flare-ups, but recently the pain from my bones has became so strong that I’m barely able to sleep at night - everything that touches bones in my legs causes excruciating pain.  

My rheumatologists just said that’s common for psoriatic arthritis, but I can’t see how can I continue to live like this, not being to sleep or do anything. even if I take Tylenol night before sleep, I’ll wake up in the middle of night not being able to continue to sleep. any ideas?
