I am sorry to hear that you are having these unpleasant sensations in your skin. First and foremost, it is important to protect your skin from sun damage. Therefore, while you are trying to figure out what is going on I strongly suggest that you avoid being in the direct sun or, at least, that you limit your time in the sun and that you also apply a good sun screen every time you are outdoors.
There are a few types of foods and plants that can cause photosensitivity. Typically, however, it is not ingesting these foods that causes the photosensitivity but, rather, when they are applied directly to the skin, say as a component of a cosmetic product, skin treatment, or lotion. Lime juice is the most typical example. Furthermore, there are many, many medications that can make you photosensitive. If you have recently started using a new cosmetic product or taking a new medication, these might be the cause.
I would suggest that you start by seeing your primary care doctor
or a dermatologist
about the issue. They will help you determine what might be the cause of your recent photosensitivity, whether a cosmetic product, medication or, rarely, other underlying medical problem.
