Your creatinine levels of 0.87 are within the normal limits(0.6 to 1.2 mg/dl in males and 0.5 to 1.1 mg/dl in females).Lipomas are benign tumors of the body.They being responsible for your symptoms are unlikely.
I feel that you should get your Hb levels and thyroid levels assessed.Anemias and thyroid diseases can cause persistent fatigue and muscle aches.Other possibilities may be
fibromyalgia ,chronic fatigue syndrome(often manifests with widespread myalgia and arthralgia, cognitive difficulties, chronic mental and physical exhaustion) ,polymyositis (means 'many muscle inflammation') and polymyalgia rheumatica(an inflammatory disorder that causes widespread muscle aching and stiffness) .
Excessive sweating also called hyperhydrosis can be due to like Hyperthyroidism or similar endocrine diseases and dermatological conditions like eczema, psoriasis
I sincerely advise you to consult a physician and get yourself evaluated for these possibilities.
Hope it helps.Take care and pls do keep us posted on how you are doing or if you have any additional queries.
