UK (NHS). 41f

Attended GP June 19th after very mild tingling (only symptom) on left hand side of body after a weird cold feeling in left buttock/hip joint starting a couple of months ago. She referred me for CT which took place on July 2nd. ANA Positive (negative for Lupus on ENA panel and negative RA and CRP though). I guess CT is just the first port of call to HOPEFULLY rule out tumour or other brain issue, appreciate MS wouldn’t show on a CT.. awaiting result (very recent eye exam showed eyesight fine, OCT fine). I generally feel fine apart from the mild tingling… I guess I just keep going back to GP if that carries on, she’s good & responsive. Nervous but keeping calm. Any UK folk got any insights into their path to diagnosis?
