[|Human|] yesterday I had hardened skin over muscles where the backbone ends (gluteus maximus muscles I guess) in my buttocks. No pain, not really itchy. For the previous 1-2 days I ate a lot of pastries with wallnuts and sugar in it. I also have some kind of arthristis in my joints (a rheumatologist from Istanbul is trying to diagnose at the moment - she says it may be spondillitis). Back to my hardened skin, I took a claritine (10 mg) last night and it looks like it is almost totally gone. Why did that happen? It was first time in my life.
[|AI|]  Hi Hope this message finds you in good health. Such kind of hardened skin occurs due to para spinal muscle spasm. Due to inflammation, the skeletal muscles under the skin go into spasm and become stiff. This occurs if you have underlying lumbar spondylitis. Get an MRI of the backbone done to diagnose. Taking muscle relaxant tablets will help. Hope your query has been answered back to me for any doubts that you may have. Kind Regards
