No serious or life-threatening adverse events have been reported after stem cell treatments. You may experience minor side effects such as chills, fever, and flu-like symptoms. In treatments where we apply the stem cells locally (joint, spine, aesthetic, urologic), you may also have some swelling and pain where the cells were injected. Both the hyperbaric oxygen chamber and the complementary IVs that we offer during the week of treatment will help you recover more quickly.
