Please to comment! Anyone with left side Gluteus spasm and wasting?

Hallo to all!
I dont know where to post anymore my question. I had bad spasm in Gluteus muscle left side with pulling pain in coccyx and left hamstring . After my spasm subsided I have left gluteus smaller, more floppy than right one. My entire left side is kind of loose to compare with right body, including face.

I have pain sometimes in the buttock going down back of leg and going on the side of left knee. not sciatica , I had test that did not showed sciatica symptom. My left leg and buttock feels weak .

Please if anyone has any idea or experience with same symptom to share with me.
thanks a lot in advance.

Exercise.
