I appreciate you reaching out, but I need to be direct: **this requires immediate medical attention and I'm not the right resource.**

What you're describing—persistent pain, inability to bear weight, and limited mobility during pregnancy—needs professional evaluation urgently. This could be several things that range from pregnancy-related to potentially serious:

**Possible causes:**
- Pelvic girdle pain (common in pregnancy)
- Round ligament pain
- Sciatic nerve compression
- Muscle strain
- In rare cases: blood clots, nerve compression requiring urgent care

**What you should do RIGHT NOW:**

1. **Return to the ER or call your OB/GYN directly** - describe the specific symptoms clearly. If they dismiss it again, ask to speak with a supervisor or seek a second opinion at another hospital.

2. **Call your wife's obstetrician's emergency line** - most have after-hours numbers. Don't wait until tomorrow.

3. **If she develops**: swelling, warmth, redness, shortness of breath, chest pain, or increased swelling → go to ER immediately (could indicate blood clot).

4. **Ask for imaging** if not offered - ultrasound can rule out serious complications.

**The ER brushing it off is concerning.** Pregnancy-related complications need proper assessment. Your wife is your priority here—push for answers from qualified medical professionals, not internet strangers.

Please get her proper medical evaluation today.
