If you have pain at the bottom of the big toe joint, up along the arch, just above the plantar fascia, you may have been told that you have this thing called FHL tenosynovitis.

"Tenosynovitis" just means that you have inflammation of the tendon sheath or tube that carries the flexor tendon down to your big toe. It helps you pull your big toe down when you push off while running. When the tendon sheath gets inflamed, it can be painful.

If you have tenosynovitis, your doctor may recommend a cortisone injection, or a Platelet Rich Plasma (PRP) injection.

So what's the difference between these two injections and why would you want one versus another?

Today on the Doc On The Run Podcast we're talking about FHL tenosynovitis injections, corticosteroids versus PRP injection.
