hi owais
My doctor told me to start "rotating" things such as for a few days use a different lotion, then a soap, then a laundry detergent, etc. Also foods, medications and fabrics may need to be rotated.
Your best bet really is to go get allergy tested.

hi
You will probably have little red bumps all over your body an if its something you ate or got into your blood stream into small cuts, you will have them on your tongue also. the best way to smooth it is get in chlorine like a pool if it starts to fade away it was probably an illergic reaction if nothing happens and becomes very ichy still see a doctor who will give you a lotion.

I dont know specifically if this is an allergic reaction but one of my friend has a black spot in his ankle which itches at times. The urge to itch gets too profound at times and he is compelled to do the same. This makes the area inflamed and the spot opens up further. Now how can this be identified whether this is an allergic reaction, and what can be the treatment for this. Has anyone experienced this before?
