It does sounds like Meralgia paresthetica.
This condition is caused by compression of the lateral femoral cutaneous, the nerve that supplies sensation to the skin surface of your thigh. It is common during pregnancy as the growing belly puts more pressure on the groin tissues. The condition would likely improve after delivery. Speak to your doctor for his/her recommendation on how to manage the symptoms, it usually involves the following:
- managing weight gain
- massage and cold treatment
- pain medication
- wearing looser clothing to take pressure off groin area
