Patellar Tendonitis for about 2 years. I have tried physical therapy but it is not really improving. I would like to give PRP a try. 
In addition,  I have been suffering with wrist pain for the past 8 months after a wrist sprain. At this point it is clear that the wrist will never heal itself. I have followed everything Physical Therapists have told me but I haven’t seen an improvement.
