I had been on blood thinner for two months ( post heart ablation procedure for afib) and also RA Dr. had me one 20mg prednisone for two months , with no red blotches , but i had IV rituxan and a week later the exact same red blotches showed up on my arms . My Dr told me to stay on prednisone for a couple more months until the rituxan ( wipes out B cells , associated to RA)
My cardi told me the blood thinner caused the red blotches ( exactly same as yours in the photo)
Red blotches did not go away , i got biopsy and the dermatologist left voice mail telling me not to worry ( did not say what these blotches were , and has not returned my calls)
So , I was having RA pain my Rheumatologist told me to take 20 then 15 then 10 then 5 mg to taper off , I took 20 mg and felt numbed and my hearing was severely impaired , 20mg was way too much for my system ! I am now taking 10 a day and plan on dropping to 5mg next for two weeks and then stop , I have only been taking prednisone for 4 months so feel that I should be able to ween myself off by December .
