About a year ago, Dr. Markle also treated me with PRP on my elbow. I did 2 rounds of that to help with the “tennis” elbow. I have not felt any pain or discomfort since. I highly recommend Dr. Markle. He was gentle and very understanding that I was super scared of the needle and used the smallest needle to help with comfort. I went straight back to working out the next day and resumed my normal routine without any problems.
