question: hi. I went to see a doctor about 4 days ago because I was on amoxicillin treatment due to tonsil infections and after I forgot to finish my dosage I went in for another one because the symptoms and signs were starting to show again. the doctor gave me an injection on my buttocks and now I feel numb around the hips and when I try to press the area I was injected I feel like some stringy thing around the numb area. what can be the cause of this numbness?
