Hello Doctor. I took Ivermectin 4 days ago for a possible scabies infestation. Today I experienced sudden pain in my hip/groin area upon walking. It s been consistent for about 5 hours now. I can find some relief when I lay flat on my back on the floor, but sitting causes terrible pain. I also was on my feet for about 6 hours yesterday at an outlet mall. I remember reading that joint pain could be a possible severe side effect from Ivermectin. Do you think I could be experiencing a side effect of the medication 4 days later or could this be a back/disc related problem. I m also having acid reflux symptoms at the same time. Add all that to the horrible rash all over my body and basically I m just a mess! I m a 58 year old female. Thank you for your time, doctor.
