Hi, I am not feeling well yesterday I had a low grade fever an have had a headache since yesterday morning I ve taken ibuprofen an took some cold medicine last nite but nothing I took helped. Today I feel worse no energy bad headache no fever I don t think and my lower back is hurting really bad I m having bad pains on my backsides not sure if it s my kidneys or what it is back there that could be making it so painful it s on both sides my right side in the lower side/ back is probably hurting the worst. I don t know if it s just the flu or if I should go to the hospital. Do u have any suggestions.
