Thank you everyone for your replies.
I intentionally omitted some details as my post was getting too long for my taste, but you have all been very kind.
I appreciate that this is a thyroid forum but I must say that my problem is yet undiagnosed and adrenal insufficiency (at this stage) is at the top of possibilities.
I went to GP again today and he suggested that I write a summary for him that he can discuss with an on-line consultant service.
So here are quite few details (that I originally wrote for him).
49 years, male, Pakistani origin. Height 173 cms. Weight 77.5 Kg. BMI around 26. Never smoked; never drank alcohol. Physically active.
No previous diagnosed problems, incidental finding of low platelet count since 2001; clinically not significant.
Chronological order of symptoms
•Skin hyperpigmentation, present for almost 2 years, affecting multiple areas over this time. Ongoing
•Light headedness :
oFirst episode last year (? November), spontaneous recovery in 3-4 hours;
o2nd episode 02/05/2017 during a game of squash, spontaneous recovery in 20-30 minutes
o May 2017 start of light headedness episodes with feeling of weakness in both lower limbs. Episodes persisted and I got admitted to A&E.
oStarted roughly around end of 2016. Stated with left shoulder (non-dominant side); Now affecting both shoulders
oSaw physio and private chiropractic Feb/Mar 2017.
oWhile in holiday in Greece, left shoulder pain got a lot worse. Saw an orthopaedic surgeon and had X-rays
oPain is not localized and there is no local tenderness that I can palpate. It feels like a deep ache and sometimes like burning.
oMuscles feel weak (subtle). Last year (23 July 2016), I climbed Ben Nevis for charity. Now I feel strain in my muscles climbing upstairs in the house
oMy shoulder muscles ache with subtle activities like teeth brushing and typing this letter
oMy friends have commented that I was never that breathless during squash last year
