I sat for a relatively longer time yesterday while traveling and also had my lunch late which caused gastric. After coming back I took a nap and woke up to leg pain..it was particularly in the knee and my legs felt little heavy. I stretched my legs and rested them in a higher position and the pain went. But it came back ( only one leg now) and I felt my thigh is swollen and hard to touch as compared to another thigh. I kept my leg on a pillow and slept but I m unable to sleep till now as there was leg pain throughout the night. I woke up and saw that the small area which was swollen had red nerve lines ( looked like spider veins). After applying moov and massaging the pain went and nerve lines also disappeared and I also changed my pant as I felt it is tight.  I was diagnosed with covid in may (home quarantined). Pls help! Thankyou
