I am an active 40 year old that up until a few weeks ago was able to walk on the treadmill at 4mph with little to no muscle soreness afterwards, but in the last few weeks I have had the following symptoms: frontal headache that comes ad goes, hip pain that is present for a few days, then goes away for a few then returns and effects may walking with no response to ibuprofen, an overall sensation throughout my body of pins and needles that comes a goes, blurred vision that comes and goes, overwhelming sense of impending doom at night with no related shortness of breath or increased heart rate and redness to my cheeks periodically. I am going to make an appointment with my provider, but I would like some insight into what to ask. thank you
