I am not an expert to help you out but I am here to tell you I hope you find out soon and feel better. Maybe ice it? Might want to call your doctor just in case.
Icy hot! I pulled a muscle under my shoulder blade a couple of weeks ago and after one app of icy hot, it felt significantly better. After two apps it was gone and didn't come back. And the main ingredient is menthol which is safe for pregnancy + it increases circulation to the area and that speeds up healing. It also works great for any those aching hip joints too.
Re: pulled muscle, help?
Hubby's goin give me a rub in a bit, he doesn't know it yet ;-)
