skin feels like sunburn

I guess you are describing pain at the surgical site. Post operative pains are normal. Some areas of initial skin numbness goes through a phase of skin nerve hypersensitivity as the numbness resolves. This is common & normal and often starts a few weeks after surgery and gradually resolves. See your surgeon for any concerns.

Many cases of shingles has been missed in ERs because of pain that no direct cause can be found and then a day or more goes by with the pain persistent and then out of the blue a rash composed of clumps of tiny pustules shows up in a geometric pattern and the diagnosis is obviously shingles. They must be treated immediately with antiviral drugs to help healing and prevent post herpetic neuralgia.

Herpes zoster, causative of "shingles" can present with pain prior to the outbreak of the skin lesions. See a doctor and if this is likely get early treatment.

What things have you used on your skin?

Obviously not for you - stay away! If you need a sauna, try steam~!

Please see your dermatologist for evaluation and to discuss treatment options.

Dr Placik: this is a concern - could be either infection or an allergic response. Best to get it looked at.

This is a problem that requires a face-to-face meeting with your doctor. In that meeting, your doctor will listen to you, perform a throrough examination and possibly order labs or other tests. Based on this information, he/she will be able to tell you what's wrong and what to do about it.

The peeling skin of the face from sun burn will be replaced fast by new cells.

This could be lipomatosis. The leg rash is probably not related. You should see a doctor
