I had my first lot of PRP injections on Thursday. It's a pretty straight forward process. I donated some blood to create the PRP. The affected region was visualised using ultrasound to identify the best position to inject the PRP. Local anaethestic was injected into the skin to reduce the discomfort from the needle used to inject the PRP. Appropriate aseptic technique was used and with ultrasound guidance, the PRP was injected into the hamstring tendons (both legs). The procedure was only mildly uncomfortable and there is a bit of residual soreness in the injection sites. Slow walking at present involves some minor discomfort. The recommendations vary between doctors. At this stage it is best to limit activities for the first week following the injections. Gentle walking is okay, but no more than that. Maybe after that week it will be okay to try a short gentle bike ride. In 3 weeks time I go back for a second round of injections and repeat the process.
