Skin or maybe blood. My life again.

Whenever I go out in the sunlight, or walk too fast , exercise, shout or do any kind of physical activity or just sit under a high power light source or wear heavy clothes My whole body suffers a sensation of someone poking me with needles all over my body , like a 100 needles everywhere at a time which makes me absolutely uncomfortable and I can't go out to do anything. This problem has been for the last 2 years and made my social life absolutely bad. I have been treated a few times but the relief stops within the 4 days of my prescribed drugs course by dermatologists being over. I wonder how long will it effect me . Well inspite of this my blood monocytes count is 00 , and I am an asthmatic patient from the last 7 years , extremely sensetive to dust, smoke etc. The only medicine that gave me proper result is WYSOLONE 10 , ,But my physician told me not to take it as it has side effects. Please help , I will be really grateful to you sir/madam. Please help me restore my life again.
