Hello, I ve been experiencing some slight headaches and a mildly sore throat for the last several days. Over the weekend I was outside at a music festival in severe heat and took a gram of cocaine and a half gram of MDMA over the course of 4 days. Could this be a side effect of the drugs (poor cut, withdrawal)? In addition, during the festival I appear to have experienced a UTI. Since then I have not felt any pain or urgency, so I think it passed. I thought it would be worth noting, though. Just want to make sure I shouldn t seek medical attention if symptoms persist.
