I've recently come down with a fever. After a check up obese found with a mild bacterial infection. I got my antibiotics for the bacterial infection, antihistamines for allergies , and cough medicine for the flu. 3 days in and I'm done with the dosage and feel a lot better but I have this horrible sharp pain in my bones on my right leg. I've been taking paracetamol to keep the pain at bay. Could be a side effect from the medication? Without pain killers I can barely funtiin from the pain.
