Yeah hope you get sorted mate,
Im same age as yourself, smoke and have 3 kids.
I sometimes get twitches which the doc put down to stress, gave me some medication bloomin heroin addicts get when recovering.. needless to say i didnt take it!
Smoking does affect circulation that affects the extremities i.e. fingers toes feel lot colder due to blood flow.
Never heard of the skin thing. Coughing blood thats the odd one and probs what they are concerned about.
Good that you have told your lass .. i suffered in silence and it did me more harm than good. Other halves do have some uses
Even if its just someone to moan at!
Keep us updated and chin up
