PsA, or something else?

Hi all, For years I've had dry, flaky, and sometime sore skin on my eyelids (no other rashes), and also been very prone to tendon injuries when playing sport. I've only just made the possible connection with PsA, but am not sure if I quite fit the bill. I've booked in with my GP, but the prospect of waiting totally in the dark for that appointment then another few months for an NHS referral is quite daunting. Any advice is much appreciated! I'm a keen rock climber at a high level, and have been injury prone for the last 10 years with issues affecting my tendons. These include my biceps tendon, patellar tendons under my knees, medial epicondyle, and various finger injuries, and my toe. The pains are never very bad (no more than 4 out of 10), and are associated with movement under load (e.g. my elbow gets worse if I do pull ups, but doesn't hurt during my day to day activities). I don't have any visible swelling, deformity or stiffness in the joints - just tendon pain that is hard to track down. My pains don't tend to be symmetrical - I've currently got a tweak in my left bicep and one in my right knee. I'm not aware of any autoimmune diseases in my family, but my dad does have eczema if that makes any odds. Am i worried over nothing, or is this pattern of easy-to-injure tendons a big red flag? Thanks in advance!
