Possible causes of lump after a chronic constipation includes venous dilatation which looks like lump, and they are generally soft.2. And hard subcutaneous lump can be hair follicular inflammation / infection.3. In this case you need to see your GP and get it examined, and if required an ultrasound to see the nature of the lump, if involving the anus - trans rectal scan will show the communicates if there are.4. Treat the constipation, fib ere died, fluids, avoid spicy, junk foods, Home remedy - sits bath (sit in the tub with warm water)5. Suggest to get appointment and get examined and treated accordingly as there are quite a large possibility of complications - which needs operative procedure if delayed. Good luck.
