Everything You Need to Know About Hyaluronic Acid Injections

Unlike steroid injections hyaluronic acid injections may take longer to start working, up to 4 weeks to full effect but can provide longer lasting pain relief with some formulations lasting up to 12 months.

What are the Advantages of Injecting Hyaluronic Acid?

Hyaluronic acid molecules can also insulate nerve endings, reducing pain signals and calming pain cells in the knees.
Hyaluronic acid is not known to be toxic to the lining of joints which is advantageous compared to corticosteroid injections. It is a substance which is also naturally produced by the body.
What to Expect During the Hyaluronic Acid Treatments
