Lipoma Removal + Inner Thighs Q&A

I've had this lump on my upper inner thigh near my pelvis for 4 years. Went to a general surgeon 3 years ago & he said it was a lipoma - at that time it could only be felt under the skin, there was no protrusion & a very faint bruising and a tiny greyish dimple about an inch from the lump. In July, it developed a pimple on top & the pimple kept bursting open, leaking pus and a little blood. Today, it is suddenly protruding from my thigh & looks like it would burst easily, like a blister.

I have terrible pain beside my knee, and down calf. Should I be concerned?

It has become cosmetically ugly. It has become hard to walk and it hurts when i walk because it rubs against my other thigh. I feel like i have to walk with my legs wide open. What can i do?

I practice Ashtanga yoga and it is very vigorous and the legs need to move in all directions and stretched out a lot. I also cycle / sim and do squats. Just wondering how soon I can go back to these activists.

I think it has to do with my vericose veins being more pronounced on that leg. Can they be worked on together. I need the veins gone as they are painful as well.

I had a lipoma removed from my inner thigh last week ,Could you please advise if the below dissolvable stitches are infected and should i visit the Doctor , he's travelling now , is it urgent ?
