My husband's left arm has hurt so badly, the doc prescribed one pack last week. He took 1 and 1/2 days worth because he had to go to the ER due to the pain. He also was short of breathing, and a blood clot in his left lung was found. ER discontinued the prednisone. He's been on dilaudid for 2 weeks as well as taking lubinox shots 2X daily and coumadin. 3 days ago, his knee doc prescribed the methypred pack again as he still thinks pain is due to inflammation in arm. Hubby finished the first pack and says he will take 2nd pack.
