I inject on Sun. and Thur. and by Fri. night I have (what feels like) a knot in my right thigh. (I only do thigh inj. with left side on Sun. with no problems and the right on Thur.) By Fri. night I have a fever and breaks by Sat. in the A.M. . This has happened 2wks. in a row and wondering if anyone has similar experience or know what's going on???
