A spot on my hip popped up tht looked like a blood blister but seemed to be attached to fat and was deep, was told its cellulitis and now its allover!

See your MD! Cellulitis is a very serious infection and if it is spreading you need to see your doctor as soon as possible to evaluate your response to treatment. Even though you are already on Bactrim, (sulfamethoxazole and trimethoprim) I would have your doc re-evaluate your treatment to determine why the redness is spreading.
