Hi I am new to the forum, so sorry in advance if not using properly. 
I am off work at the moment with an allergic reaction, to what who knows, my doctor says looks like bites. Have been surfing the net and think I may have Lupus:-
Allergic to Septrin (2 occ whilst a child 2yrs & 10yrs, swollen lips/tongue and rash all over)
Suffered from migraines from teens
Glandullar Fever at 12yrs
Cronic knee pain leading to 4 operations to tighten ligaments (still suffer pain)
I get swollen lymp nodes under my arm pits when feeling unwell
Always tired, can't get myself going some days. Makes me feel like I am lazy and there is nothing really wrong.
When I have had blood tests in the past have had to be repeated due to low white cell count.
Fainting & low blood pressure.
I had a lumber puncture, nerve conduction tests and blood test probably about 10yrs ago when I was under the doctor for the knee pain, which resulted in the knee operations.
Should I go back to my GP, feel like I am always there, will they already know from the tests I had?
