 [ Symptoms ] the zoloft my doctor prescribed five weeks ago is not working i have been referred to a psychiatrist what can i expect [ Disease ] i am sorry to hear you are dealing with this these types of things can be very annoying i suggest you have this lump examined by a doctor it could be a cyst that needs to be drained if the lump contains pus it could eventually cause an infection and if you squeeze it to the point you break the skin to allow the fluid out then you risk getting bacteria into that wound and causing a different type of infection you could have a pilonidal cyst which definitely requires a doctor is attention i can think of several other possible causes for the lump you describe which is why you should have an examination better to get it diagnosed and taken care of than to allow it to possible evolve into something serious wishing you well
