6 days ago I woke up in the middle of the night with multiple bug bites 6 bites in all, 1 on back of head, 1 on arm, 2 on left leg, 2 on right leg. The bites were initially very large welts like when i get bit by mosquitos, and very painful but not itchy, when I got up in the morning they reduced in size significantly but became very itchy, I ended up scratching them till they bled then i stopped. They then became bigger and inflammed for 2 days, and 4 days in i started to notice bruising around my legs, the muscle in the back of my left calf felt sore as if i pulled it, 5 mini bruises near the bites and 3 bruises on bites, and 1 large bruise near a bite seen in pic. I dont recall ever bumping my knees so i dont know where these bruises are coming from. Today I dont feel sore in the left calf, never had a fever since bitten and feel ok except for stiff neck but that could be due to bad sleeping posture.
Should i be worried?
