Sorry, about a delayed response - unfortunately, I didn't realize you had reached out to me. It seems that your symptoms are consistent with hypersensitivity type reaction to UV exposure. Basically, your immune systtem can mount an inflammatory response in the skin, when exposed to UV radiation in sun light.
Recommendations to prevent or decrease this type of reaction are to use sunscreens strictly, during the day time. The sunscreens with Zinc or Titanium (physical block) are better than chemical sunscreens alone. Sunscreens should be at least SPF 30. Sunscreens should be used throughout the year, even during winter months.
If you experience a reaction, in spite of using sunscreens, you can improve the symptoms by using 1% Hydrocortisone cream three times a day x 1-2 days as needed (available over the counter).
Hope this helps address your question.
