How To Treat A Rash Which Is Up The Bottom Of The Legs,arms And Shoulders?

i HAD A BAD SKIN RASH WHICH WAS UP THE BOTTOM OF MY LEGS, DOWN MY ARMS AND ON MY SHOULDERS. THE RASH WAS LIKE BLISTERS AND REALLY HURT. I WENT TO A SPANISH DOCTOR WHEN IT FIRST APPEARED AND SHE SAID IT WAS AN ALERGY. AFTER I HAD HAD THE RASH A FEW DAYS MY EYE WENT A LITTLE STRANGE ALMOST AS IF A SPECK OF SOMETHING WAS GOING ACCROSS MY EYE, IT HAPPENED IN BRIGHT SUNLIGHT AND WAS FINE IN THE EVENING. THE RASH TOOK ABOUT 7 WEEKS TO CLEAR UP AND I THOUGHT MY EYE WOULD GET BETTER WHEN THE RASH DISAPPEARED, BUT IT DIDN`T IT IS STILL A LITTLE STRANGE (MY VISION IS NOT BLURRED AND IT DOESN´T HURT AT ALL) i HAVE SINCE SPOKEN TO MY SISTER IN ENGLAND WHO SUSPECTS THAT I HAVE HAD SHINGLES AS SHE SAID THERE WAS AN EPIDEMIC IN SOUTH LONDON BEFORE CHRISTMAS AND I HAD EXACTLY THE SAME SYMPTOMS AS A FRIEND OF HERS- AND I HAD JUST COME BACK FROM VISITING FRIENDS WHO LIVE IN LONDON. IS THERE ANYTHING I CAN TAKE TO RID THIS FROM MY SYSTEM?i AM 51 YRS OLD 5FT 5 AND 59KILOS. i DO MONITOR MY BLOOD PRESSURE REGULARLY AS I HAD A STROKE 20 YRS AGO (VERY MINOR ONE) I HAVE A DOCTOR PHOBIA WHICH SOUNDS STUPID,BUT CAUSES ME TO PASS OUT AND WHEN I COME AROUND I VOMIT AND ARE REALLY SICK FOR OVER A WEEK. THIS IS THE REAOSON I WOULD LIKE TO TRY AND GET SOME MEDICINE AT THE PHARMACY TO GET RID OF ANY VIRUS I MAY HAVE THANKYOU
