I'm not sure how to send pictures using this website form. I have no itching. This has happened since I started taking the 100mg/day of doxycycline. If it's a blood coagulation problem from the doxy, should I discontinue now, or wait to see my PCP about it first? The ring-type bruise on my left upper thigh is reddish; the large rings around my underarms are a bit faded from how they were at first, are a light XXXXXXX now- they were reddish at first. There's also a streaky looking red mark across the top of my left thigh that is not the result of trauma.

Brief Answer:
You can use attach report option for sending image

Detailed Answer:
Hello,
I have studied your case. It can be due to Doxycline also. There is no progress in the lesion and they are not causing you any trouble so no need to stop Doxycline just now. Wait for your PCP to see.
I would suggest you to avoid applying any cream or soap in that region. Avoid wearing tight undergarments or cloths. Keep that are dry.
I am waiting for images.
Thanks
