ok, I have a paper wasp bite on inside of the forearm close to the fold at the elbow. Was stung 2 days ago. Still continuing to swell at the moment. its about 11x10 inches,extremely red,hard,almost like blistered skin at the center and then gradually goes to pink. I have taken benadryl since, saw clinic dr today, prescribed prednisone. 30mg daily for 7 days. I took the first dose a few hours ago. Did this because thought it might help but now prefer to not continue taking the prednisone.Can I just let nature take its course and let the swelling go down on its own without the prednisone. I have had this type of reaction to just a flee bite. Its always a localised allergy. At what point do I have to say , ok I have to take the prednisone for sure? if I must take the prednisone, (5mg tablets) can I gradually decrease the dosage after the 2nd day?go down to 1 tablet on the last day.
