Samll Red Patches across limbs. Too.

Small red patches across hands and legs, that come and go away. Now I am getting bruises on thighs, legs and hands. These bruises were not having any problem until now. They come and go away on their own. But there was one bruise just above the knee on my left leg that turns into kind of a lymph node. Earlier It's color was reddish, now it's a mixture of red and blue. I am also getting pale patches of the size of 2 cm. Attached are the photos of the small red patches and 2cm nodes and pale patches for your reference. Sometimes I get a long breath, sometimes I feel fatigue also I feel kind of a dizziness or like I will fall down even though I am sitting. My brain goes for a quick short dizziness. Losing my health and weight too. Thanks
