BAD ALLERGY

My whole body itches from head to toe feeling like something pinging me inside, it been a month now since it first started to me like this, first it started in my thighs to the back of the shoulder then later to the neck and the face, i thought of not going to see doctor coz maybe it will disappear after some time in one or two days. days have gone with out any change and the itching spreading other parts of my body giving me headache and anxiety . i couldnt wait anymore since it was getting worse so i went to the school clinic and prescribed Allergic medicine which was very light for my Allergy. there was no change and am running out of time so i need to get control of this strange feeling before it gets out of control, i was so confused and worried about what am going through, i have never been like this, being Allergic to something but this is totally different feeling.

One night i browsed the net and searched for what could be the root cause of this itching and which kind of disorders have these symptoms, the pages never stop reading different stories and answers. but most of them stressed on one issue, thats jaundice which also creates skin itching. then i wrote down everything and looked across to how i felt, almost the same but should be proved by the lab before any medication, i felt so disturbed and annoyed by my own body. I finished taking the tablets it wasnt that helpful and after a week i went to my doctor and explained to him all that i went through, she said that maybe its the weather or something that you got Allergic to. i told her that i should test for Jaundice coz it might be that, i was so curious about that since i never got ill of that, i presented my test papers to the lab which later they gave the urine container and took blood samples for liver test, my nerves were very high and was anxious about the whole thing. after an hour later they called me back and took the results to the Doctor, i couldnt wait her review the result so i asked her to quickly tell me, she said in surety voice that am Healthy and that i dont have Jaundice. i felt relieved for sometime, but again asked myself what could be the root cause of these, nothing to translate how i feel when my body itches. I told my Doctor that my Itching is not something only to consider as Allergic but she smiled back and said that Allergy can be worse than you think, to me allergy is just some kind of disorder you feel for some short period of time and later gets away. its different and even worse to some extend, the doctor prescribed me some tablets which she said will be helpfull.
The tablets look different than the previous one and bigger in size, am not that good in medications coz i dont like them. especially i prefer injection than tablets, they have sour taste and makes me feel vomit, i bought the tablets back and finished using them. i felt just little bit better than before when i was on the drugs but after i finished taking them things got worse than even before, my body is so sensitive to everything even the wind. i dont know what to do and am so worried about this, i have appointment with my Doctor tomorrow but i cant wait to meet him. i just want to know what could be this, if allergic then whats the best way to control if not whats then.
