Activity is not inherently harmful to a bunion. Problems more often arise from rapid load increases, repeated pressure in unsuitable shoes or an activity that exceeds the current capacity of the joint and surrounding tissues.
Use the response later that day and the following morning to guide progression. A temporary mild awareness that settles may be acceptable; escalating pain, swelling or altered gait indicates that the load should be adjusted.
Increase duration or intensity gradually rather than changing several variables together.
Use low-impact conditioning when forefoot symptoms flare.
Match footwear to walking, running, court sport or occupational demands.
Avoid persistent limping; investigate the cause if gait does not normalise.
After surgery, follow the staged return plan until bone, strength and gait have recovered.
Does running make every bunion worse?
No. Some people run comfortably with a bunion or after surgery. Symptoms depend on deformity, joint condition, training load, shoe fit and mechanics. Pain should guide assessment, not a blanket prohibition.
