I’m really sorry she’s in pain — that’s stressful, especially when you can’t get in to see the doctor right away.
I can’t diagnose without seeing it, but I can help you think through how urgent this might be.
🚨 Go to urgent care / ER now if she has:
- Rapidly increasing swelling
- Redness spreading around the area
- Warmth and severe tenderness
- Fever
- Red streaks going up the foot/leg
- Numbness or inability to move her toes
- Severe pain that’s worsening quickly
- A recent puncture wound (nail, splinter, bite)
Those could signal infection, abscess, or something that shouldn’t wait.
🟡 Common (Less Dangerous) Causes of a Painful Lump on the Foot
- Blister or blood blister
- Plantar wart
- Insect bite reaction
- Ganglion cyst
- Bruised tissue from minor trauma
- Ingrown toenail (if near toes)
- Plantar fibroma (firm lump in arch)
If she can barely walk, that suggests either:
- Significant inflammation
- Pressure on a nerve
- Infection
- Or a deep bruise
🏠 What You Can Do Tonight (If No Emergency Signs)
- Rest & elevate the foot.
- Apply ice (15–20 minutes at a time, wrapped in cloth).
- Give age-appropriate pain relief (acetaminophen or ibuprofen if she can safely take it).
- Avoid tight shoes — use soft sandals or keep pressure off the area.
- Don’t try to cut, squeeze, or pop anything.
If you’re comfortable, you can tell me:
- How old is she?
- Where exactly is the lump (heel, arch, toe, top of foot)?
- Is it red? Warm? Soft or hard?
- Did she injure it recently?
That will help me guide you better on whether this sounds urgent or likely safe to monitor until next week.
