July 18 2023 I had same both on my inner thighs came up 2 weeks after sports injury I’m very fit active I was intensively training the last two weeks of June and July 3. My left leg started to swell up and then July 4. I couldn’t even walk my inner knees to my thighs were so big they had no muscle. It was scary. I have been to 15 doctors to vascular‘s. No one thought anything about the pictures I showed them and I’m still not right the swelling continued on the left side, especially to numbing and tingling in my feet and my calves my forearm to my fingers.
