Yeah slow stretching after tiger balm massage or an epsom salt bath will start to help. Just remember to be patient. Sometimes it takes a while for the stiffness to start to release.

I get it often, Epsom salt compresses help sometimes. Tiger Balm massaged in and compression pants. Stretches and weight training in a slow gentle progression.

I have that also only it is in my left, upper thigh. Pulled my groin doing Yoga too, in the left leg( I tried to do a move that was definitely for much younger people). Anyway, so I am having multiple problems/pain in my left leg causing me not to be able to walk without a limp. My fibromyalgia has caused much pain, exhaustion, sleepless nights, etc, and mind fog during the day. I have had this since my late thirties...I am now 62...and have been on medicine for at least 20 years; it took the edge off of the pain. However, it isn't working now and I get worse every day/week/month. It is an awful disease and I am so tired of feeling this way. I go back to the doctor this month (October 22, 2020) so, I will see what my doctor can do for me now. God Bless all of you and hang there!
