Sore Red Line Behind Knee. Red Itchy Rash On Lower Legs. Suggestions To Aid Recovery?

Hi, I have a sore red line that has appeared behind my knee the line is horizontal across the whole back of my knee. The sore looks and feels a bit like a graze. When this appeared I also had a red itchy rash on my lower legs. This rash has calmed down now, but there is still a few signs remaining. I have recently done an abnormal amount of walking which I think might be the cause, as I am finding that my legs are now stiff and tight, and I do not have the same range of motion I had before when bending. I m sure my legs will recover soon, but is there any advise you can give me to aid my recovery. I am stretching my legs daily and apart from keeping my legs clean I m not to sure what else I can do.

Hi

Looks like you have developed intertrigo over the knee folds.

This occurs due to maceration of skin at the folds due to increased sweating.

Now this leads to fungal infection most commonly at the folds.
You might need to apply a topical antifungal cream and take some oral antifungals along.
take antihistamines for the itching.

Hope it helps
