I know of a remedy which may help alleviate such ailment. Don't know whether you have Chinese medical ointment available in your country. I have a good effective one here though. It consists of:
Methyl Salicylate 30%
White Oil 19%
Menthol Cystal 14%
Eucalyptus Oil 8%
Essential Oil 12%
Base 9%
Turpentine Oil 8%
Rub the oil gently every night on your affected area before you go to sleep (the best moment for bodily recovery or recuperation). Wrap the same area up and then sleep through the night with it. I know of a brand called Nefful from Japan which manufactures a range of health improvement products as in clothing, limb supports and undergarments. A pair of their leg wrap support, though quite pricey, may reinforce your recovery.
My apologies though, and don't get me wrong, I am not here to promote any product. I am merely giving you a tested remedy which I conjecture may help you too.
Beside, therapy should help you too. That goes to say you should exercise your leg, for example, leg raise. But, I don't know which part of your leg is unwell. You may like to find out the exercises specifically designated to tackle the particular area.
Lastly, keep praying and execute what you have identified you need to do. Prayer plus actions.
May you be soonly relieved from your discomfort. Amen.
