question: hi i started using the sunbed twice or 3 times a week for 3 minutes a week for a month before i went abroad in march then used it twice after. around that time i stated having feelings that my chest was tight sometimes anfd when i flew while i iwas on the plane it came back and lasted all flight and i went on it again twice and since then the pain has dissapeared. howvevr i iwent on the sunbed earlier tonight and the tightness has come back. however has eased off now. what do u think it could be? im 25 yrs old 5ft 6 and 10 and half stone, no previous probs
