I was misdiagnosed with proximal hamstring tendonosis in jan 2013, and after many PRP treatments and much PT, and over a year off the bike without change in symptoms, I got a second opinion.
Basically what happened was a dull aching pain when i sat at work, but not on the bike. Then it got bad enough to feel on the bike. Since the treatments I was still feeling the pain, and a buzzing sensation in the same area when I would lie down to sleep at night.
The second opinion is neuropathy, nerve compression, or something similar related to the Adductor Magnus and/or Obdurator Internus. The doc found no tenderness at the proximal hamstring tendon, but did a stretch test that was able to reproduce the pain, more medial to the tuberosity than the hamstring. The doc prescribed message, and I am due for a nerve test in a couple of weeks, and she also started me on Neurontin to reboot my nerve signals. The massage was pretty crazy...google Obdurator Internur images, and you'll understand. Hopefully we'll have a treatment plan soon and i can get back on the bike (it has been a sad sad year without the bike and the company of my riding buddies).
I am excited to have a diagnosis that makes more sense, but am curious if anyone else has had an issue like this. The only other thing i have found in research is a condition that makes the naughty bits numb (which is def not an issue for me).
