I was just wondering it this can be a side effect of ibuprofen. I have used Ibuprofen plenty before and I don't think so. Also, I was running fever and sore throat for 2 days before all the finger issues suddenly showed up, could that have contributed to it? The only other thing is that some old injuries' scars became painfull that day too, all of this lasted for about 2 days, except the nail spots, they will have to grow out of course. I think i am mainly wondering about some sort of Strep-A antigen reaction(rheumatic fever type thing). Any thoughts?
