Compression recovery and therapy can be excellent options to help manage various conditions. Side effects associated with compression recovery are typically mild and avoidable. Problems such as skin irritation, bacterial or fungal infection, discomfort, or pain, and swelling of the toe area or lower foot can occur in some cases. But ensuring the compression device is well fitted, replaced when worn out, and used as instructed are easy ways to avoid this. A 2018 study in the Journal of Applied Physiology found that intermittent compression could improve exercise performance and recovery by increasing limb blood flow. Swelling can also be reduced with compression boots. Repetitive stress causes microtears in your muscles no matter what kind of run you do. If you're recovering properly (staying off your feet, elevating your legs, resting), swelling will go away naturally. However, compression can shorten the amount of rest you may need by preventing swelling from pooling in a certain area after a run.
