What Causes ULQ Abdominal And Back Pain With Outbreak Of Red Rashes?

First, Thank you. It s a series of symptoms starting in Feb 2016to now. I am 60 non smoker, eat very well, not overweight , no medications. Never sick - last flu was 10 yr ago. YYYY@YYYY 1)Started the end of Feb 16 ...severe pain in L lower rib- upper L quadrant. Thought I had broken my ribs. 2) Two weeks later awoke late at night, couldn t breath - was diagnosed with Pneumonia...by PA. Took first antibiotic in 25 yrs K-Pac.- 5 days. Pneumonia?/coughing cleared. 3) A week later my back left side where pain was/is ....broke out in very red itchy rash - shingles they say! That fairly much cleared up - painful but now just itchy red rash which spreads up down L side...also now R. But not like a shingles rash now ....just red itchy spots. 4) Was feeling somewhat better BUT ---my digestion/regularity lots of /bloating! ...very out of sorts. 5) Then a week ago my whole diaphragm area very painful - left & right & in front.No back pain at all. Now, cannot lift anything heavy, move easily, and am very tired ...but all feels like it in the ribs. Sternum now also a bit painful. No seeming Gall Bladder or liver pain. 6)The pain seems to really be worse in lower outer ribs....now on both sides - though does hurt on breathing when thr lungs expand. If you cupped your hands and held the lower outer rib area ---both sides --- if I press inward it s extremely painful. Thank-you for any thoughts you may have.
