Hi, thanks for writing to HCM.
Your charlie horse symptoms & sharp stabbing pain
of thigh could be due to Dehydration
(secondary to alcohol intake) or mineral depletion (low potassium or calcium).Spontaneous bruise
can occur due to many causes like ageing, drug induced, Diabetes, Cirrhosis
etc. So a detailed clinical evaluation is needed to establish a diagnosis.
Hope this information is helpful. Good day
