Don't know whether anyone will be able to offer any advice but I feel I've done myself an injury. Basically, after advice from a physio had been taking great care to avoid movement that worsens my spd, and symptoms had dramatically eased. But today my 2.5 yo dd ran away from me towards a busy road and I had to run to stop her. I felt a crunching sensation between my legs, as i ran, and have gone from reasonably good mobility to hardly being able to walk. Is there anything I can do? I am 35 weeks and have a 4 and 2 yo who I need to look after, no family or support nearby. Any advice greatly appreciated!
