36 weeks, leg pain and light headed

36 weeks tomorrow. Both today and yesterday I have been getting sharp pains on the upper inside of my RHS leg.

The pain is eye watering and takes my breath away. Following an episode, my leg feels tingly. It has also been feeling weak on/ off for the last week.

Over the last couple of days I have also been feeling light headed and shaky on and off.

Any experience with this or thoughts?

Ps: have left a message with midwife but they are always slow responding
