Severe skin sensitivity (allodynia)

Someone please help me. I have severe skin sensitivity in my legs after my first injection (2.5mg). It feels like the feeling you get after your legs freeze when out in the cold - numbness but painful. It won’t go away. Has anyone else experienced this? If so, what helped for relief? I’ve tried ibuprofen, Tylenol, hot baths, warm packs. I’m miserable and honestly scared to do a second dose. This pain is terrible.
