Few days back I had to go to the emergency due to excruciating pain on period 1st day. They gave me injection for the pain in my buttocks. After few hour my right thigh above knee feels numbs. I have pain, burning sensation, difficulty walking and now I have got small boils under the thigh. What could be the reason. How to overcome this? Will this be cured? Also note Out of 3 injection I took only one for pain. I have attached the picture of prescription . Kindly guide me , thank you in advance. Could it be nerve damage?
