@wendydvb Congratulations on your transplant and how wonderful your sister was able to donate to you! What kind of a protocol you are on, is it non steroidal? Meaning no Prednisone as a medication. That is what my husband's transplant team used for the longest time and that is why they had to biopsy his new kidney. He has been on prednisone 2.5 mg once a day for the last several months due to low white blood count, but they will be titrating him off of that in the next few months. I think that muscle soreness and discomfort can be a normal sign due to your body getting used to activity again and the introduction of medications.
