Hi , last couple of days had a severe back pain, took ibuprofen, no relief. later took two tabs of Aleve, about 12 hours later, have developed a non-itchy rash spots on right chest, right armpit and right back. Ceased taking Aleve, which was quite old. I m 55 yrs old, fit and feel fine. No prior allergic reaction and no other side effects. Some sites say call dr asap. Others, are less alarmist. Just asking about this
