I tripped and hit my thigh on the top corner of a stone wall and formed a massive dint in my legon sunday, it swelled up pretty fast and formed a hard lump around the bump. It hurt alot with all forms of movement and i couldnt walk on it for around 4 hours. I used ice eleveation and compression for it. Yesterday it was still realy swollen and hurt when i tried to bend my leg but was fine to walk as long as i diddnt take to big of steps. It also come up with a bruise and was still hard but without the dint. I did a light quad stretch and found that although painfull it gave me more mobility in my leg. At the end of the day i did about half an hour of streching and strengthining exersizes which removed nearly all the pain and just left the hardnes however it was then quite week when walking.
This morning it was realy sore again but not as bad, i did some stretching and strengthing again which helped but caused my hip to click. I can now bend it most of the way although it still hurts a fair bit and is realy week. I cant use it for stairs, to lower my body to chairs or floor and it feels like it will colaps if i step to big.

If streches and strengthning is helping should i keep doing it or go to a physio?
